建立了地铁车辆车轮与曲线区段钢轨接触的有限元模型,应用有限元参数二次规划法分析这一三维轮轨接触问题.对不同轴重和横向力作用下的轮轨接触模型分别进行计算,得出了大量的轮轨接触应力的分布及变化规律.这些计算结果将有助于找到缓解钢轨侧磨的方法.
The finite element model of the rail contact between the wheel and the curved section of metro vehicle was established and the contact problem of the three-dimensional wheel and rail was analyzed by using the quadratic programming method of finite element method.The wheel and rail contact models under different axle loads and lateral forces Calculated and obtained a large number of wheel-rail contact stress distribution and variation of these calculations will help find ways to ease rail side grinding.
