摘要
建立CRH380B型动车组车辆多体动力学模型,通过仿真计算轮轨接触参数,再通过FASTSIM算法结合Archard磨耗模型预测其磨耗量,并与实际车辆磨耗数据进行对比。结果表明,仿真与实际测量的车轮型面磨耗发展情况相似。并对影响车轮磨耗的参数进行数值仿真分析,主要计算在不同轮轨接触磨耗系数和不同钢轨道床扣件垂向及横向刚度变化情况下的车轮型面磨耗变化,结果表明降低摩擦系数可有效降低车轮磨耗,而钢轨道床扣件的刚度对车轮磨耗影响很小。
The car multi-body dynamics model for CRH380B EMU is built to calculate the wheel-rail contact parameters through simulation. The wear is predicted with FASTS1M algorithm and Archard wear model. Then the results are compared with the actual car wear data. It shows that the wheel profile wear development between the simulation and the actual measurement are similar. Then the author carries out numerical simulation analysis on the parameters influencing wheel wear, it mainly calculates the wheel profile wear change under different wheel-rail contact wear coefficient, different vertical and transverse stiffness of the rail bed fasteners. The results prove that the reduction of wear coefficient can effectively reduce the wheel wear while the stiffness of rail bed fasteners has minor impact on the wheel wear.
