高速万向轴传动式动力车动力学性能分析

Dynamic Behavior Analysis of High Speed Power Vehicle with Universal Coupling

采用NLSA程序，对万向轴传动式高速动力车进行了运动稳定性分析。采用美国AAR的NUCARS程序和德国的MEDYNA程序，分析了动力车的非线性动态曲线通过，非线性时域里向和横向响应，以及频域垂向横向响应等动力学性能。确定了万向轴传动式高速动力车转向架的悬挂参数，并在保证性能的前提下方便了制造，有效地配合了转向架的设计工作。

This paper analyses the running stability of high speed power vehicle with universal coupling by the use of NLSA and studies the nonlinear dynamic curve negotiation and the vertical and lateral response in time domain and frequency domain by the use of NUCARS of AAR and MEDYNA. The suspension parameters of the power vehicle are determined to the advantage of facilitating the production of the power vehicle and in coordination with the design of its bogies.
