摘要

提出了一种计算车厢间联轴器受力的方法，其中包括车轮磨损造成的车轮踏面几何形状与圆锥形不同所产生的力的组成部分。车轮磨损的同时会产生额外的惯性力，影响车轮的滚动特性以及车轮与钢轨之间的接触力，这些惯性力也包含在构成列车纵向动力的联轴器受力计算中。力对垂直轨道不规则性的影响也考虑在内。

Influence of the Wheel Tread Geometry on the Longitudinal Dynamics of a Train

A method for calculating the forces between intercar couplings is presented, which includes components of forces caused by the difference in the geometry of wheel tread surfaces from a conical shape, resulting from wheel wear. Wheel wear is accompanied by the appearance of additional inertia forces that affect the rolling characteristics of the wheel and the contact forces between the wheels and the rails, which are also included in the calculation of forces in the couplings that form the longitudinal dynamics of the train. The dependence of forces on vertical track irregularities is taken into account.
