| 摘 要： | 为满足列车动力学仿真对轮轨接触点位置的精度要求,采用解析方法建立轮轨空间接触几何的约束方程组,并给出其在二维轮轨接触几何情形时的简化形式.以S1002车轮踏面和UIC60钢轨为例,基于符号计算平台Maple软件对该约束方程组进行求解,得到轮轨接触几何参数.结果表明:二维轮轨接触时的滚动半径差、接触角差、接触点在车轮踏面...

| Abstract: | To meet the demand for the precise solution of the wheel-rail contact points in train dynamics simulation,the constraint equations for wheel-rail spatial contact geometry were established by analytical method,and the simplified equations under two-dimensional wheel-rail contact geometry assumption were given.Wheel tread S1002 and rail profile UIC60 were used as examples to solve this set of constraint equations based on the symbolic computation platform in Maple,and the parameters of wheel-rail contact geom... |
