【摘要】 针对铁道行业中的车辆曲线通过问题,运用SIMPACK虚拟样机技术,建立了高速车辆-轨道动力学仿真模型,对我国60kg/m钢轨断面及LM型车轮踏面进行了开发。针对高速铁路和客运专线,探讨了在车辆速度为200km/h的条件下,曲线半径、超高、缓和曲线长和轨底坡等线路参数对车辆安全性及舒适性的影响。对今后我国高速铁路及客运专线的修建具有一定的指导意义。更多还原

【Abstract】 In this paper, aimed at the problem of curve negotiation in railway, high-speed vehicle-track dynamical model is built. Secondary development is done on the basis of 60kg/m rail section and LM wheel tread used in China. Based on high-speed railway and passenger dedicated line, discussion is done on influence of safety and comfort of vehicle caused by the line parameters such as curve radius, cant, length of transition curve and rail cant, when the train negotiate railway curve at the speed of 200km/h. The research will be of significance for the construction of high-speed railway and passenger dedicated line in the future.更多还原
