插入连杆。
A4与A3销钉连接
再取两断面对齐。
完成后得
点右键添加集。
A3与A6销钉连接，同时断面对齐。
五、运动分析
节臂与机架连接的销钉处设置一个伺服电机，设置轮廓，规范选“位置”，“模”选常数“-75.91”，点确定。
打开分析定义，运行获得汽车直行时传动机构位置，如图
重新编辑定义伺服电机，使其反向；
设置轮廓，规范选“速度”，“模”选常数“10”，点确定。
打开分析定义，时间设置为3，这样最大外转角即为30度。
点运行。
运行结果为左转弯最大位置，如图
点击测量结果。
新建测量1，以节臂与连杆销钉连接的轴线为测量点，类型选位置，评估方法选每个时间步长。
类似地新建测量2，唯一不同在于测量点选取梯形臂与连杆销钉连接的轴线。
分别出图
分别点文件选输出Excel。
图表如下图
β角的Excel复制到α角Excel里，再加入理想值，以方便对比。
结果如下表
