摘要

采用多体系统动力学软件SIMPACK建立了某型重载货运电力机车动力学模型，首先用初始激励法以AAR5、AAR4和AAR3轨道不平顺作为初始激扰，得到该机车的蛇行临界速度；然后，基于澳大利亚AS 7509.1标准和UIC 518标准，分析了该机车不同轨道不平顺下的安全运行速度。结果表明，该机车横向稳定性满足各种线路运行要求，随着轨道不平顺的加剧，机车的安全运行速度有一定的下降，横向性能变差；横向稳定性分析中，可以根据不同线路状况采用不同的仿真方法。

Abstract

A certain heavy locomotive dynamic model of the locomotive was established with multi-rigid-body dynamics software SIMPACK. By using AAR5, AAR4 and AAR3 track irregularities as the initial turbulence, the serpentine critical velocity of locomotive was obtained by the initial motivation method. Then, based on the Australian standard and UIC 518 standards, safety operation speed of the locomotive under different track irregularity was obtained. The results showed that: The lateral stability of the locomotive could meet the requirements of safe operation; with track irregularity increasing, safety operation speed would decrease, and the lateral stability of locomotive would be worse. According to different line conditions, different simulation methods in lateral stability simulation analysis should be adopted.
