摘要
通过多刚体动力学仿真软件,针对某一机车分别建立了完整模型和简化模型;通过采用不同的抗蛇行临界速度的计算方法对这2种模型进行研究,并结合实际线路试验结果,得出不同的初始条件对仿真结果有很大的影响,采用失稳状态为初始条件的计算方法得到的值最接近实际值的结论。
With the simulation software of multi-body dynamics, a complete and simplified model is built respectively for a locomotive. Two models are studied with calculation methods of different anti-hunting critical speeds. Combined with practical line test results, it is concluded that different initial conditions are highly influential on the simulation results and the value closest to the practical one is gained via the calculation method with unsteady state as initial condition.
