TV broadcast bodywork design requirementsIntroduce bodywork design Install broadcast is a comprehensive system engineering, the body is the complex system is an important part of. In the broadcast, the body part in carrying out all broadcast video recording needed, audio and peripheral equipment, provide an outside the workplace. Not only such, still must ensure the safety equipmentoperation and smooth transhipment, The design quality, not only directly affect the task of broadcast programs, but also to the whole system of safe transport equipment.Bodywork design, is the first consideration in the broadcast of the design, the first thing to do, It will have a direct relationship to other system design.Bodywork designing technical requirements for design, should according to the hull of broadcast equipment size and purpose to choose, The general is installed cameras number, the risk is bigger also. According to the former chapter 8, use the broadcast cameras, can consider to choose medium broadcast. In television broadcast often faced severe external environment, and considering carrying equipment and broadcast task too many factors such as particularity, broadcast in the modification of car when the car to the body, structure and so on a series of chassis project careful overall consideration, through special design and processing, can meet the basic requirements of television. The following are the technical requirements for design body.The safety performance of the broadcast must conform to the state auto industry standards, car body processing and chassis USES the overseas broadcast depot exterior processing technology, size and payload must conform to the state department of traffic regulations. Car chassis and selection: international famous brand high-end products, the truck chassis on all equipment shall be loaded under the condition of the truck with 20% less than 200 surplus, engine, air suspension design, power electronic speed, hydraulic control 85KM/h, air conditioning system design, driving with anti-lock brakes (ABS) emission standards, with European standards, 111 2.5 meters wide.Car body requirements: TiZong compartments 10-11 meters long, no more than is 3.8 meters high and wide 2.5 meters, the right side is four meters long pull box. Box body use fixed number of year more than 15 years, the car body structure of aluminum alloy frame, with high strength and insulation, Material requirement is accord with international standard of environmental protection, flame retardant materials. Vehicle requirements, dustproof, waterproof and sealed anti-rust, anticorrosion, preventing electromagnetic interference, antistatic, After the integration of box body must be rain experiment (including the side after pulling open box, when jose) experiments, the static pressure side tilt impact experiment. The surface with high strength and durable products in the process of paint, paint baking room. Body after processing, vehicle has left from the Angle, finally, from the smallest drive vehicle spacing, minimum turning radius basic technical parameters.Body: the space layout design requirements, and fully consider the reasonable layout of the camera, lens, earphone, tripod, cable, microphone, tools and equipment accessories storage space. For the car fixed equipment should consider appropriate carry scheme.In the national standard of vehicles, within the scope of the space as far as possible, spacious internal headroom maximization, the lateral pull section 2.2 meters, internal clear part and internal headroom wife 2.0 cars, cars GaoCheng 4 meters in vitro.According to the different type of programme production division, scientific and reasonable utilization of working space. The workspace shouldHave partition, and pass the adornment with door, audio broadcasting acoustic requirements.Car chassis and selectionGenerally speaking, the car chassis and is generally together of choose and buy, the first to calculate the weight, then the broadcast and calculate the maximum weight, total quality, Choose total capacity calculation model is bigger than that.This design calculation, for example (hereinafter data for each half xiang estimated) :The total weight of two car electronic equipment nominal total weight (1 ton) + internal cables and connectors total weight (0.3 tons) ten outsideCable and cable reels total weight (0.5 tons of air-conditioning equipment and power) and total weight (l) + containing side and tons of heavy trunk TiZong compartments (5 tons) + car chassis total weight (5.5 tons) = 13.8 tons. Maximum loading 17.25 tons.Additionally, want to consider the traffic situation and task destination of local geography environment, For been poor road conditions or the environment, should choose the output power of the engine and have left corner to corner and Outlines the chassis (in after modification, this part of the parameters change), In order to protect the precision bearing, should choose the equipment with air suspension design of air suspension system (increase chassis, can effectively increase the stability and the operation is necessary in the smallest increase car from the ground clearance and increase the car go right Angle of comparison, through calculation. Head and chassis selection for: Germany, MANLE18.280 car chassis and 18 tons, the highest quality of loading, electronic power output of 280 horsepower maximum speed did 85k: / h, exhaust emission standard requirements, chassis for double-axis braking, rear suspension system (air adjusting range to 14Omm - 80mm), to 18.5 Angle (left), (6.5 Angle, hydraulic steering system, ABS system.Bodywork design types and carsBody type selection, according to the technical requirements for broadcast medium body choice to build. At present, we have the choice of two types: the body dragged hang cabinet type body and direct box type bodywork. Straight hang cabinet is cabinet of body directly placed in vehicle chassis. Drag hanging box type body is only a few on-axis (l), or on the trailer to move. Now broadcast and dimensions of the body, but are strict standard practice. Straight hang cabinet body type hanging box type than drag of small size, because the body size by means of transport together for this decision, countries have limited body length. Generally speaking, it adopts the body from 8 to 10 metres, car - 10-12 meters to. Drag hang cabinet type body USES is 13.6 meters standards body length, but due to the design needs may be more or less. For example, do the length of 18 meters above the hull. Considering the high road, there is through the general standard limits, cannot exceed 4 meters high, usually for 3.7-390 meters, width is 2.5 meters. Because of this part of the city and the surrounding roads are narrow, many sites around the gate, and narrow space, low broadcast to think of site near the area is restricted, models. Additionally, the demand is moderate, considering the number of these factors, so the choice of pull with lateral direct box type car. Hang cabinet type body straight by lateral pull cars, can expand workspace technology area, reduce the length of the body and the height, make whole have shorter turning radius, and good road through sex, increase flexibility of moving body. Drag hanging bodywork, high center of gravity, stability, not only in the city driving speed is slow, even in the highway is compared with straight, and drag hang trailer for highway and car case typed driver requirement is high. However, until the body hangs box type, the car chassis and broadcast is permanently connected compartment, Because of the reliability of the car and car box part is the reliability of the chassis, therefore the reliability of the system reliability of normal operation. However, in the car with tow lock, in case.Car body designThe whole system design is compartments of the follow-up work, it relates to broadcast other system design. In the initial stage of design, construction, as a first consideration should choose the material, then compartments of air conditioning, consider bodywork layout and installation requirements of technical equipment, etc; put At the same time, the design details must be considered the perfect follow-up function. The car body from design to completion, need at least 4 to 5 months. Various processes are certain order, therefore, in the design of the system should have planning and management. Car layout. The car compartment, broadcast early material body USES a lot of hardwood as their framework with the period, the most commercial body design, In the 1960s began to aluminum frame, aluminum envelope special design direction. 4 when turning radius: automotive steering wheel steering, car outside the center, under support vehicles, track circle radius. Steering wheel turned to limit position for minimum radius of turn ramming turn radius of glory. Now, a better and more stable fiber materials of aluminium surface (aluminum) chromate salt a sandwich board structure of interlining, Therefore, most use these new materials and structure to build the whole body, the conventional materials is added as internal store content ark, entrances, and other auxiliary area.Through the comparison, FRP (GRP6 or FRP6) or aluminium surface material qualitative sheet intercalation sandwiches are high, with design, long service life, magnetic, insulation, sound insulation, etc.Sandwich board, according to the different surface material, is divided into: steel surface materials and aluminum/GRP surface materials. When the materials of large area, steel surface material can produce vertical crease, and aluminum/GRP surface materials (not crease) consecutive. In addition, the surface of aluminum excellent in reason, including anodized, apparent into processing, coating and electroplating, therefore, to broadcast, choose aluminium surface or surface suitable materials.For frame materials (stainless steel and aluminium), we fully consider the various factors. Stainless steel welding joint with high mechanical strength, rigidity and fatigue resistance, can satisfy the demand for hull integrity structure. Among the austenitic stainless steel, with excellent energy absorption ability, considering safety construction, it is elected. In the vehicle weight after comparison, choose steel material than aluminum material slightly heavier 10%. Through comparing, aluminum plate type: the surface of metal sheet intercalation sandwiches and mixed structure of the body. This bodywork austenitic stainless steel body frame structure (profiles do using stainless steel welding aluminum easier than because of stainless steel, aluminum) sandwiches sandwich plate surface of car do. For Windows and doors, choose body surface sandwich sandwich plate GRP. Box body side sandwich sandwich plate thickness 50 cars, total body top sheet intercalation 55mm thick sandwiches, the total volume of reinforcement and the cabins lockers by certain thickness of stainless steel. This new design of body structure, give full play to the advantages of two kinds of materials, and make a new body than the current domestic other body, has more advantages than traditional vehicle weight of car-body reduce 40%, Aluminum/GRP materials sandwich insulation sandwich board, make car is very quiet, Body structure is due to decorate, Car body USES sandwich plate containing special since maintain sandwich super structure, high strength, good resistance to impact and the support ability, to ensure the long-term stability of the hull structure, can reduce maintenance costs. In addition, sophisticatedelectronics wooden store content ark, the table at the edge of the wooden edge material selection, was processed by the hardwood, insect and moistureproof, Rappel/abseil stations should be at the man-made fabrics such as screen window instead of natural.The design and processing of carriageWhen a detailed schedule chart, after the completion of the body frame can from inside to outside began to build. From the bodywork design to completion probably need 4-5 months, then consider all equipment purchase, If the plan is completed in body, thoughtful, you can install equipment. At the beginning of the process, frame first is fixed on the car chassis rack. For special car body, chassis rack and body between the special elastic adhesive filling, can guarantee the bodywork multiple components in their long remain relatively fixed position, extended body life. When the body, the engineer will cabins sandwich plate design requirements by large Windows, doors and maintenance (etc), calculated platform, dig, then without fixed whole car chassis. For different area, we adopt profiles between sheet buckles after heightenning strength the special adhesive elastic method, minimum connection screw fastening and reduce the use of welding, hardware are stainless steel. In addition, in need of welding, choose good welding materials electroplating. On roof and floor, also used similar plank and processing method, But in these areas under the floor and big flower board inside, must design the air conditioning intake on spear strike price, exhaust pipe and cable etc. Air inlet 11 feet by ten working area through porous ceiling is completed, therefore essential in insulation layer under the appropriate design of pipe, In the porous metal plate, aluminum materials, and should choose the eye. The air filter condensation prevention. In order to avoid air turbulence generated in pipe noise, the design of many such pipe, the number of air conditioning, these specifications depending on pipes adopts non-toxic ammoniac Yun foam body. For simplified equipment maintenance, design the level off and maintenance. After repair, below half open platform made floor, ceiling upper, which makes it very convenient maintenance maintenance personnel. Maintain doors equipped with gas leading hoop, can easily open doors: all of the mouth, and the dust, shimei, and under the unified set with a key can open all the lock of the door. On both sides of the car body skirt locker, design for the camera lens, the tripod, backup, cable, tools and equipment store empty, They are designed to key can open mode. Because the body with cars, so in design and installation of the bottom side pull the two squares retractable cable protection pipe, through the cable from here to the body of internal also should be carefully considered. Within the sound broadcast require special environment, and therefore must choose sound-absorbing materials of wall and ceiling, we choose is porous sound-absorbing board (belong to impedance compound aluminum mufflers), internal filling composite sound-absorbing material. Car floor selects anti-static floor, easy cleaning. In the equipment design, the frame and the console keep back the gap in 50, This is after wiring brought convenient, also increased the equipment of cabinet, in order to control temperature air circulation. For the broadcast from appearance, can choose their own cars in the standard color swatches, so the color to the international standard RAL9010 color car choose pure white (to go out at the camera calibration quick white balance). After the integration, car body 10.06 presidents, total height 3.75 m, width 2.5 m, right side, 4m bandwidth, can pull lm. The manufacturer to rain experiment box body (including the lateral spread), full pull box when inclined to static experiment, high impact experiment, Meet the design requirements. When our car modified in the rear car modification, rear skirt do for design of dress, car tilting such modified normal operation technical parameters for the final horn, left: from high 437mm, driving the minimum distance from the ground. Minimum turning radius, the vehicle 9.65 m.Bodywork layout designThe number of hull layout including partition door, the work area, etc. According to the practice of the body, broadcastIs divided into three separate areas: director area, centralization, audio area. With the setting TV production, more standardized, scientific and set each region also distribution and the corresponding locations.电视转播车车体的设计要求车体设计介绍安装转播车是一项综合性的系统工程，车体是这个复杂系统的重要组成部分。在整个转播车中，车体部分承载了所有转播录制所需要的视频、音频及周边设备，提供了室外工作的场所。不仅如此，车体还必须保障设备的安全运行和顺利转运;其设计的好坏，不仅直接影响节目制播任务的完成，还关系到运送整个系统设备的安全。车体设计，是在转播车设计中最先考虑的，也是首先要做的;它的好坏直接关系到以后其他系统的设计。车体设计技术要求车体设计，应该按照转播车的设备规模和使用目的来选择;一般是安装摄像机的讯道数越多，车体也就越大。按照前章所述，使用8台摄像机的转播车，可以考虑选择中型转播车。鉴于电视转播车常常面临的恶劣外部环境，以及考虑到承载设备的娇贵性和转播任务的特殊性等诸多因素，转播车车体在改装时必须对车的底盘、车体结构等一系列项目进行周密的全盘考虑，通过特殊设计和精心加工，才能够满足电视转播的基本要求。下面给出车体设计的技术要求。转播车的安全性能必须符合国家汽车行业的相关标准，车厢体加工及底盘采用国外转播车厂加工技术，外型尺寸及有效载荷必须符合国家交通部门的相关法规。车头和底盘选型要求:国际知名品牌的高端产品，底盘的载重应在装载所有设备的情况下留有20%以上的载重余量，引擎不小于200马力，空气悬挂设计，电子限速85KM/h，液压控制驾驶系统，空调设计，配备ABS(刹车防抱死)，尾气排放标准符合欧标准，车宽2.5米。车厢体要求:厢体总长10-11米，整车高不超过3.8米，宽2.5米，右部有4米长的侧拉箱。厢体使用年限十五年以上，车厢体框架由铝合金夹层结构组成，有较高的强度和绝缘性;所用材料要求是符合国际标准的环保、阻燃材料。整车要求密封，防尘、防水、防锈、防腐蚀，防电磁干扰、防静电;集成后必须对厢体进行淋雨实验(包括侧拉箱展开后)，满荷时进行静态侧倾斜实验，防高压冲击实验。外表面采用环保型高强度耐用产品油漆，整个喷漆过程在烤漆房进行。车体加工后，要求车辆有合适的离去角、最后端离地高、行驶中最小离地间距、整车最小转弯半径等基本技术参数。车体布局设计要求:空间布局合理，并充分考虑摄像机、镜头、耳机、三脚架、备用线缆、话筒、工具等设备器材及其附件的存放空间。对于非车内固定设备应当考虑合适的携带方案。在国家车辆标准范围内，空间尽可能的宽敞，车厢体内部净高最大化，非侧拉部分内部净高2.2米，侧拉厢部分内部净高妻2.0米，车厢体外高成4米。按照节目制作的不同工种划分工作区，科学合理的利用空间。各工作区之间应当有隔断，并有通行门，音频区的装饰符合广播声学要求。车头和底盘选型一般来说，车头和底盘一般是连在一起选购的，首先要计算整个转播车的载重量，然后加上自重，计算出其最大总质量;选择总承重略大于计算值的型号叫。以此设计计算为例(以下数据为半湘各估算值):车总重二电子设备标称总重(1吨)+内部电缆和连接头总重 (0.3吨)十外部电缆及电缆盘总重 (0.5吨)+空调设备和电源总重(l吨)+含侧拉厢后车厢体总重(5吨)+车底盘总重(5.5吨)=13.8吨;最大装载质量17.25吨。另外，要考虑任务目的地道路通行状况和当地的地理环境;对于多山地或者道路条件较差的环境，应选择输出功率较大的引擎和拥有较大接近角和离去角竺的底盘(在车体改装后，这部分参数会变化);为了保护承载的精密设备，应选择带有空气悬挂设计的底盘(增加空气悬挂系统，能有效地增加汽车行运中的稳定性和在必要时增加汽车的最小离地间隙右、加大汽车的离去角。通过计算比较，对车头和底盘的选型为:德国MANLE18.280车头和底盘，最大装载质量18吨，最高输出功率280马力，电子行最高车速85k:/h，尾气排放标准达到要求，底盘为双轴制动，后桥有空气悬挂系统(调整范围到80mm-14Omm)，接近角(18.5)，离去角(6.5)，有液压助力转向系统，有ABS系统。车体类型及厢体设计车体类型选择依据技术要求，此转播车按照中型车体选择建造。目前，供我们选择的车体有两种类型:拖挂箱体式车体和直挂箱体式车体。直挂箱体式车体是箱体直接被安置在车辆底盘上。拖挂箱体式车体是仅有后轴(l个或几个)的，靠拖车头来移动。现在转播车车体尺寸并没有严格的标准，但有惯例。直挂箱体式车体要比拖挂箱体式车体的尺寸小，这是因为车体尺寸由连在一起的运输工具决定，国家对这样的车体长度有一定的限定。一般来说，它采用的车体从8米到10米之间，车总长达到10- 12米。拖挂箱体式车体采用的是13.6米的标准车体，但长度由于设计的需求可能或多或少。例如，有做到长度达到18米以上的车体。考虑到道路通过性，高度是有标准限制的，一般不能超过4米，通常的高度为3.7- 3.9米，宽度总是2.5米。由于本市和周边城市的部分道路比较狭窄，许多场地周围空间狭小，并且大门较低，转播车要想到达现场较近的地区工作，车型受到了限制。另外，设需求的讯道数适中，考虑到这些因素，因此选择了带侧拉厢的直挂箱体式车体。直挂箱体式车体采用侧拉厢技术，可以扩大工作空间面积，减小车体的长度和高度，使整车有较小的转弯半径，和较好的道路通过性，增加车体移动的灵活性。拖挂式车体庞大、重心较高，故稳定度较差，不仅在市内行车速度慢，即使在高速公路上也难与直挂车相比，还有拖挂箱体式车体对于公路和驾驶员的要求也很高。但是，直挂箱体式车体的转播车，其车底盘和车厢体是永久连接的;由于车箱体部分的可靠性加上车底盘的可靠性是整个系统的可靠性，因此其正常行驶的可靠性降低了。不过，可以在车内配备拖锁，以备万一。车厢体设计厢体设计是整个系统后续工作的基础，它关系到转播车其它系统的设计。在厢体设计的最初阶段，要首先考虑选择构造厢体的材料，然后考虑车体布局、空调的需求和安装、技术设备的摆放等等;同时在设计的细节上，必须考虑后续功能的完善。整个车厢体从设计到完工，至少需要4到5个月。各种工序都是有一定的顺序，因此，在设计时要有系统的规划和管理。车布局图。车厢体的选材早期，转播车车厢体使用了大量的硬木作为它们的框架，这跟那个时期多数商用车体设计一致;60年代开始转向铝骨架、铝蒙皮的专用车设计方向。4转半径:汽车转向时，汽车外侧转向轮的中心、下面在车辆支承平面，轨迹圆半径。转向盘转到极限位置时的转夯半径为最小转夸半径。现在，有了更好的玻璃钢材料和更稳定的铝表面(铝一铬酸盐处理)三明治夹层板材结构的出现;因此，大多采用这些新型材料和结构去构建整
