摘要

本文应用改进的29自由度车辆动态曲线模型，研究了货车低速行驶在过渡曲线上的车轮爬升脱轨安全性。在模型中，考虑了轨道的不规则性。该模型成功地模拟了车辆爬升到轨道顶部的全过程。本文详细分析了周期性不规范对脱轨的影响。结果表明，横向水平对低速货车在过渡曲线上的脱轨性能有显著影响。

Influence of periodic irregularities on wheel climb derailment safety of a freight car running on a transition curve

The paper applies the modified vehicle dynamic curving model with 29 degrees of freedom to study wheel climb derailment safety of a freight car running at a low speed on a transition curve. In the model, track irregularities are taken into account. The model is successfully used to simulate the whole process of a vehicle climbing up to the top of rail. In the paper, influence of periodic irregularities on derailment is analyzed in detail. The results demonstrate that cross level exerts a marked effect on derailment performance of a freight car with low speeds on a transition curve.
