内容简介：

车辆试验拉压传感器标定装置设计摘 要在实践操作过程中，往往需要知道测量出传动机构中拉压力的大小，了解将动力以不同的力学形式传递给工作装置。通常采用压电式传感器放入测试试验台，通过采集，处理压电信号来表征拉压力的测量。本装置采用电动机作为滑动螺旋机构的进给、回退的动力源。蜗轮蜗杆实现减速增扭，在蜗杆上加装转动手柄以及机械式千斤顶此两者作为对拉压传感器力的加载。最大载荷50000N。 同类产品设计中，由于该套试验装置应用多在车辆上，我国的汽车产业自建国以来虽发展迅速，但核心研发的试验能力不强，所以国内产品较少且水平有限。国外由于汽车产业发展历史悠久，科研实力强，特别是欧美等西方发达国家设备精良，试验人才多，技术上领先于国内。我们应多汲取国外的先进技术、设备，在此基础上加以消化改进最终转化为自己的。而在测量技术上，更多的朝向智能化、科技化、微量化、信息化、生物智能化的方向发展。因此在机构设计，理论研究中要有创新意识，不断的发展前进。关键词：传感器，测量，信号，车辆CALIBRATION DEVICE DESIGN OF PULL AND PRESS SENSOR OF VEHICLE EXPERIMENTABSTRACTIn the process of practicing an operation in, usually need to know the diagraph size which spreads to move to pull pressure in the organization, understanding deliver the motive equips for work with the different mechanics form.Usually adopt to press an electricity type to spread a feeling machine to put into the test experiment set, pass to collect, handle to press telecommunication number to come to token to pull the diagraph of pressure.The this device adoption electric motor is to glide enter of spiral organization to, return to back of motive source.The Gua round Gua pole carries out deceleration to increase to twist and add to turn to begin handle and machine type jack this both on the Gua pole Be press to spread the feeling machine add of dint to carry towards pull.Biggest carry the lotus 50000 Ns.(can overload 75000 Ns) The same kind product design medium, because of that set of experiment the device be much more applied on the vehicle, our country of car industry from found a nation although development quick, core development of experiment the ability be not strong, so local product less and level are limited.Abroad because of car industry development the history be long, the research real strenght is strong, especially Europe, the United States, Japan waits a western and flourishing and national equipments excellent, experiment talented person many, lead in the technique with domestic.We should draw advanced technique of take the abroad more, equipments, take in to digest to improve an end conversion on this foundation for own of.But morely turn toward the intelligence in measuring a technique, technological, little by little turn, information-based, the living creature intelligence turn of the direction develop.Therefore design in the organization, theories research in have to have innovation consciousness, continuously of develop headway.KEY WORDS: sensor, measurement, signal, vehicle目 录第一章 绪论.1第二章 滑动螺旋传动设计.22.1螺旋副传动的设计.22.2滑动螺旋副的结构与材料.2 2.3滑动螺旋副的特点.32.4滑动螺旋副的应用.32.5滑动螺旋传动参数的选择与计算.32.5.1 耐磨性.42.5.2 自锁条件.52.5.3 螺杆强度.52.5.4 验算螺纹强度.52.5.5 螺杆的稳定性.62.5.6 横向振动.62.5.7 机械效率.62.5.8 驱动转矩.6第三章 蜗轮蜗杆传动设计.73.1蜗杆传动的特点.73.2 蜗杆传动的类型.73.3 蜗杆传动的主要参数及其选择.73.4 蜗杆传动的失效形式.103.5 蜗杆材料的选则.103.6 蜗杆受力分析.103.7 蜗轮齿面接触疲劳强度计算.103.8 蜗杆传动的效率.133.9 蜗杆轴的强度验算.13第四章 轴承的选择与校核.174.1 蜗杆轴上两轴承校核.174.2 螺杆上轴承校核.17第五章 轴承盖的选取.18第六章 电动机的选取.196.1 电动机类型和结构形式.196.2 电动机的容量.196.3 电动机的转速.20第七章 联轴器的选取. 22第八章 键的选取与校核. 238.1 键连接的类型. 238.2 键的选择. 238.3 键的校核. 23 第九章 拉压
