The lrv to be constructed shall comprise 3 ( three ) cars with motor and trailer bogies . cars located at the ends of the vehicle shall have driver cabs 每列轻轨车由装有动力转向架和拖车转向架的三辆车组成。每列轻轨车的头/尾车有司机室。
2.
Then the dynamics calculating model is built from the structure of the trailer bogie . the mathematical equations are deduced and the principle of dynamics calculation is explained . the simulation model of trailer is set up by using the multiple bodies simulation program simpack 根据研制的拖车转向架的结构建立了拖车的动力学计算模型；推导了拖车动力学数学方程，阐述了动力学计算原理；并利用多体系统仿真软件simpack建立拖车的仿真计算模型。
