主动导向转向架的多体动力学仿真与试验研究

对主动导向转向架的半车模型进行了多体动力学计算，并进行了滚动台试验，计算结果和试验结果基本一致。将半车模型扩展为整车模型后，进行了计算分析，研究结果表明，主动导向转向架可以大大提高转向架的曲线通过性能。

Multibody Dynamics Simulation and Experimental Evaluation for Active-Bogie-Steering Bogie

The multibody dynamics calculation is made on the basis of the half-vehicle model with active steering bogie,and the test is carried out on the rolling test rig. The calculation result is basically the same as the test result. When the half-vehicle model is developed into the full-vehicle model, the calculation and analysis are made. The research result shows that the active steering bogie can greatly improve the curve negotiation performance of bogies.
