| 摘 要： | 根据轮轨空间动态耦合关系, 提出了一种根据轮轨接触点位置进行脱轨评定的直接方法, 可用于对机车车辆动力学安全性分析评价。阐述了通过轮轨接触点进行脱轨评判的原理和采用此方法的优点。作为例子, 运用货车-轨道空间耦合模型, 对C62A货车曲线通过进行了脱轨仿真计算。仿真结果表明, 在仿真计算时采用此方法非常行之有效, 评判直观、可靠。

| Abstract: | According to the coupling relation of wheel rail contact,a direct method is proposed to evaluate wheel derailment based on the wheel rail contact point.The advantage and the principle of the method are described. As an example, wheel derailment was simulated for a full scale freight car negotiating a curve from the point of view of vehicle track coupling dynamics.The results show that this principle is a very good method to evaluate vehicle derailment especially in simulation of railway vehicle dynamics.1 tab,3 figs,5 refs. |
