总体设计手册-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。输出基本尺寸定义卜J初班人机_L程分析及目I 标定及工&谀计目标他出初期定义CCP/I更效件/旃开发件I动力总减旬手布置基本的法律法规定义卜cop件初步布置一j6迪立乂斯件位置限制图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、COW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：1-2(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 所示。图1-2(2)确定踏板和踵点位置，如图 1-3所示。(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前排H图1-5图1-4(4)确定方向盘位置，如图 1-5所示。(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,方向盘各种位置对驾驶员和后排乘客进彳T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(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。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 1-151.1.2.1.4 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。1.1.2.2.1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。图 1-14(14)绘制二维俯视图，如图 1-15所示。1.1.2.2第二版总布置图完善布置草图1呜LL5就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 息位置；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娟性、5炽性人体相关要求，以验证是否满足95娟性头部进入要求、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 Angle-Front234A40-2Back Angle-Second275A42-1Hip Angle-Front956A42-2Hip Angle-Second947A44-1Knee Angle-Front1138A44-2Knee Angle-Second799A46-1Ankle Angle-Front8710A46-2Ankle Angle-Second8811A60-1Vision Angle To Upper DLO-Windshield1712A60-2Vision Angle To Upper DLO-Backlight3.913A61-1Vision Angle To lower DLO-Windshield614A61-2Vision Angle To lower DLO-Backlight3.315A106-1Angle Of Approach16.616A106-2Angle Of Departure36.117A121-1Window Slope Angle-Windshield60.418A121-2Window Slope Angle-Backlight38.419A147Ramp Breakover Angle16.120H5-1SgRP To Ground-Front571表1-1 （续）21H5-2SgRP To Ground-Second61722H11-1Entrance Height -Front79823H11-2Entrance Height-Second77424H13Steering Wheel To Thigh Line6325H14Eyellipse To Bottom Of Inner Rearview Mirror1726H17Accelerator Heel Point To Steering Wheel Center68427H25-1Belt Height-Front44828H25-2Belt Height-Rear45829H30-1Seat Height-Front32730H30-2Seat Height-Second40031H49Eyellipse To Top Of Steering Wheel6832H50-1Upper-Body Opening To Ground-Front1369.533H50-2Upper-Body Opening To Ground-Second138934H56-1D-Point To Floor-Front22235H56-2D-Point To Floor-Second29236H61-1Effective Head Room-Front100337H61-2Effective Head Room-Second94738H70-1SgRP Z Coordinate-Front35039H70-2SgRP Z Coordinate-Second39040H74Steering Wheel to Cushion19341H100Body Height151042H101Vehicle Height, Maximum184743H103-1Bumper To Ground-Front14844H103-2Bumper To Ground-Rear25445H111-1Rocker panel Height-Front15946H111-2Rocker panel Height-Rear16747H142-1Cowl Point Z Coordinate777.848H142-2Deck Point Z Coordinate49H143-1Cowl Point to Ground50H143-2Deck Point to Ground51H115-1Step Height-Front35952H115-2Step Height-Second36753H156Ground Clearance13854H195Liftover Height66855H201Cargo Height74456H251Liftgate to Ground180257L7Steering Wheel Torso Clearance389表1-1 （续）58L11Accelerator Heel Point to Steering Wheel Center35759L13Brake Pedal Knee Clearance60360L22Steering Wheel To Seat Back49661L30Front Of Dash-X Coordinate16762L31-1SgRP X Coordinate-Front126363L31-2SgRP X Coordinate-Second204164L32SgRP-Second To Rear Centerline42265L33Maximum Leg Room -
