摘要:
为了解决山区小半径曲线下车辆运行安全性低、平稳性差等问题,基于车辆轨道耦合动力学建立某型轨道客运车辆动力学模型;给出线路参数方程及车辆动力学方程,并对其进行仿真计算,分析曲线半径、缓和曲线长度、欠超高等山区工况曲线几何参数对轨道客运车辆通过性能的影响.研究结果表明:在一定范围内,轮轨横向力、轮轴横向力、脱轨系数、轮重减载率等曲线通过性能指标均随着圆曲线半径、缓和曲线长度、欠超高的增大而有明显的降幅,车辆曲线通过性能增强,安全性和平稳性提高.
Abstract:
In order to solve the problem of low safety and poor stability of vehicles under small radius curve in mountainous area, the dynamic model of a passenger railway vehicle was established based on vehicle-rail coupling dynamics. The parameters of the train line and vehicle dynamics equations were provided. The simulation calculation was carried out. The influence of geometric parameters such as curve radius, transition curve length and under-super high mountain operating conditions on the passing performance of rail passenger vehicles was analyzed and discussed. The results show that within a certain range, the performance indexes such as wheel-rail lateral force, axle lateral force, derailment coefficient and wheel load reduction rate obviously decrease with the increase of radius of circle curve, length of relaxation curve and under-high parameter so that the vehicle curve through performance was enhanced and the safety and stability were improved.
