总体所设计手册总布置图1.1 总布置图绘制1.1.1 意义根据新产品规划和概念设计确定车身总布置方案，然后再绘制总布置草图，然后开始进一步的造型设计。其中整车总布置草图的绘制对后期的开发设计起到依据和指导作用。1.1.2 总布置草图的绘制1.1.2.1 第一版总布置图-概念草图1.1.2.1.1 相关输入及流程为了给造型提供工程依据和下一步设计提供指导，绘制出总布置概念草图。总布置草图的绘制开始于项目预研阶段，根据新产品的规划，对竞品车进行扫描分析，根据发动机舱初步布置数据得出初步的整车限制尺寸和人机工程目标；依照相应的法律法规要求，并根据现有产品尽可能的考虑通用化的前提下确定车身总布置方案。总布置概念草图的绘制时间及相关流程见图1-1所示。图1-1 总布置草图绘制时间及流程1.1.2.1.2 总布置草图内容草图阶段的总布置图，主要是对造型的输入，体现总布置的基本硬点参数，其中最重要的是H点的位置，H点是整车的设计参考点，必须在早期准确地确定，一旦更改将对整个前期的布置设计及项目进度产生重大的影响。在草图阶段的总布置图中，主要体现如下内容：1、H点坐标，人机内部空间等相关参数；2、整车外廓尺寸，包括长、宽、高、轮距、轴距、前悬、后悬；3、法规要求及设计目标；4、COP零件的状态；5.三种载荷状态的地面线；6、各种限制面；7、其他，如车门形式、玻璃曲率等。1.1.2.1.3 绘制概念草图步骤在绘制概念草图之前，是在已经了解项目定位、对项目有了初步策划方案，并且对竞品车或对标车进行了大量分析的前提下开始绘制。通常，概念草图的绘制需要如下步骤：（1）首先建立车身坐标系，“国标”定义的“整车坐标系”。通过空载或设计载荷时车轮中心（左、右前轮和左、右后轮）及地板门槛纵平面来确定整车坐标系。然后摆放车姿，如图1-2所示。图1-2（2）确定踏板和踵点位置，如图1-3所示。后踵点前踵点踏板组图1-3（3）先确定前排H点位置，再确定后排H点位置，如图1-4所示。后排H点前排H点图1-4（4）确定方向盘位置，如图1-5所示。方向盘各种位置图1-5（5）用人机工程软件校核H点、踵点和方向盘的位置关系，并进行优化。根据优化后的结果，对驾驶员和后排乘客进行坐姿摆放，如图1-6所示。 图1-6（6）确定发动机和发动机盖板的位置，定义C点位置，如图1-7所示。图1-7顶棚最高位置限制面（7）根据头部空间的需要，确定顶棚的位置，如果必要参照对标车确定，如图1-8所示。图1-8（8）按照法规确定保险杠的位置，如图1-9所示。后保险杠位置前保险杠位置图1-9（9）确定体现车身主要尺寸的轮廓线或限制面，如图1-10所示。 图1-10（10）确定前后风挡玻璃的形状和位置，如图1-11所示。图1-11（11）前方视野校核，根据眼点位置，风挡玻璃开口尺寸，发动机盖板位置，校核前方视野，如图1-12所示。图1-12（12）绘制二维正视图，如图1-13所示。图1-13（13）绘制二维侧视图，如图1-14所示。图1-14（14）绘制二维俯视图，如图1-15所示。图1-151.1.2.1.4 概念草图输出绘制完成的第一版总布置图-概念草图连同车型描述表、工程设计目标或者储物空间定义等文件一同输出造型，指导造型设计。1.1.2.2 第二版总布置图-完善布置草图1.1.2.2.1 相关输入第二版总布置图开始于造型冻结阶段，输入完整的CAS数据，根据底盘确定的空、半、满三状态下的轮心位置，在第一版总布置图的基础上绘制第二版总布置图。1.1.2.2.2 第二版总布置图内容在第二版总布置图中，与第一版相比图形主要增加内容如下，并增加尺寸列表：1、完善第一版总布置图，明确整车内、外部尺寸；根据最终确定的三状态轮心坐标修正地面线；2、增加相关运动件的运动位置，如发动机罩、后背门运动位置、前后门各锁止位置；3、增加三踏板尤其是油门踏板的行程两极限位置、换档手柄各使用位置、手刹拉起和放松两示意位置；4、增加方向盘遮挡仪表可视性及三踏板相对位置关系，可用单独的小图表示；5、发动机罩及后背门使用位置处增加95%男性、5%女性人体相关要求，以验证是否满足95%男性头部进入要求、5%女性开启关闭要求；6、俯视图上增加A柱障碍角标注等。1.1.2.3 第三版总布置图-最终布置图第三版总布置图开始于A面冻结阶段，根据冻结后的A面数据完善第二版总布置图，完善相关尺寸列表并归档。完整的尺寸列表内容如表1-1所示。表1-1zxNO.New CodeDimensionYaris-Value1A18Steering Wheel Angle27.92A19Track rise angle4.83A40-1Back
