摘要
为探讨高速铁路钢轨磨耗预测方法,本文依托西成客运专线鄠邑至新场街高坡区段,运用多体动力学软件UM建立钢轨磨耗预测模型,分析了通过总重50 Mt时钢轨磨耗情况,结果表明预测模型与实际情况大致相符;探讨了随通过总重的增加钢轨磨耗的变化规律,分析得到钢轨打磨周期设置成40 Mt较为合理。最后,对各项动力学指标随通过总重的变化进行了简要分析。
In order to probe into the prediction method of rail wear of high-speed railway,this paper uses the multi-body kinetics software UM to establish a rail wear prediction model based on the high slope section from Huyi to Xinchang Street of Xi’an-Chengdu Passenger Dedicated Line,and analyzes the rail wear when the total weight is 50 Mt. The results show that the prediction model is roughly consistent with the actual situation. The change rule of rail wear with the increase of total passing weight is discussed,and it is reasonable to set the rail grinding cycle to 40 Mt. Finally,the changes in kinetic indexes with the total weight were analyzed briefly.
