摘要
为了提高机车横向动力学性能,利用多体动力学软件建立250 km/h高速机车动力学模型,通过计算分析机车的横向稳定性,得出合理的悬挂参数,判断其非线性临界速度且分析在直线上机车的悬挂参数对机车横向平稳性的影响,分析研究了不同悬挂参数对改善机车横向动力学的影响。
To improve the lateral dynamic performance of locomotives, a whole dynamics model of 250 km/h level above is established by using dynamic software to research the locomotive lateral stability, to obtain reasonable suspension,to judge its nonlinear critical speed and analyze influence of locomotive suspension on its lateral riding quality in line. The effect of the different suspension to improve locomotive lateral dynamics is discussed.
