动力学参数对出口铁路客车扭曲试验的影响
|
摘要
目前国内对于轨道车辆扭曲试验无论是开展现场试验还是进行仿真计算都没有成熟的经验,通过对比不同扭曲试验标准表明了出口铁路客车扭曲试验标准明显严苛。利用SIMPACK软件针对某型出口客车进行动力学建模,并依据试验标准进行了扭曲试验仿真计算,同时开展现场扭曲试验进行仿真计算结果验证。无论仿真计算还是现场试验结果均表明原有动力学参数的扭曲试验结果远超出试验标准的规定值。利用试验设计DOE方法调查了上千种不同动力学参数组合下对扭曲试验结果的影响,获得了动力学关键参数对于车辆扭曲试验的影响度,并基于各种不同参数的影响度重新优化了动力学参数。结果表明,所提出的车辆扭曲试验仿真计算流程弥补了仿真方面的不足,另一方面动力学参数影响度可以为企业产品设计提供理论依据,保证了出口车辆扭曲试验的通过性。
At present, there is no mature experience in the field of railway vehicle twist test, whether it is to carry out field test or simulation calculation. By comparing different twist test standards, it shows that the railway vehicle twist test standard of exported country is quite strict. The SIMPACK software was used to model the dynamics of an exported vehicle, and the calculation of twist test simulation was carried out according to the test standard. At the same time, the field twist test was carried out to verify the simulation results. Both the simulation calculation and the field test results show that the twist test results of the original kinetic parameters far exceed the specified values of the test standard. The experimental design DOE method was used to investigate the influence of thousands of different kinetic parameters on the results of the twist test. The influence of the key parameters of the dynamics on the vehicle twist test was obtained, and the original parameters were re-optimized based on the influence of various parameters. The results show that the shortcomings of simulation has been made up by the calculation process of proposed vehicle twist test. On the other hand, the influence of dynamic parameters on railway vehicle twist test can provide theoretical basis for enterprise product design and ensure the reasonability in the exported vehicle twist test.
