李军的小车模型在matlab和adams 联合仿真中的问题

ipyuren

我们采用matlab的simulink与adams联合仿真，在联合仿真中，如果后轮驱动采用motion驱动是有问题的，程序报错，总是说一些joint不存在，一些motion不存在。看似联合仿真过程中，模型中的'JOINT_30'和'JOINT_29'以及他们上面附加的运动没有被引入。

但是同样的模型，如果采用Force驱动后轮进行联合仿真则没有问题。不知这是什么原因。



另外说明一下，这个模型在admas里面单独运行，前后轮都用motion驱动，没有问题

还有就是ADAMS单独运行没有问题，但是和matlab链接就是出现轮子解体的问题，不知为什么？
