摘　　要：将后轮独立车轮转向架运用到地铁拖车中,利用SIMPACK动力学分析软件对其进行分析,证明其稳定性和小曲线通过能力均优于传统地铁拖车。讨论轴距对新型地铁车辆的影响,使其在保证稳定性的前提下进一步提高曲线通过性能。Putting the bogie with independently rotating wheels for roar axle into use in metro trailer, the model is set up and analyzed by SIMPACK dynamics analysis software. It is proved the stability and small curve passing performance of the new style metro trailer is better than the traditional one. The influence to the new style metro trailer＇s dynamics of changing axle distance is studied to achieve better curve passing performance ensuring stability.
