| 摘 要： | 轨面短波不平顺是轮轨作用力的主要影响因素。通过分析实测轨面短波不平顺数据，利用仿真计算研究不同轨面不平顺、不同运行条件下的车辆动力响应，比较分析动力响应计算结果有利于了解短波不平顺对运行列车的安全性和稳定性的影响。最后的结果分析为现场轨面短波不平顺的维修养护控制值提供一定的理论依据，并建议了轨面不平顺的控制值。

| Abstract: | The primary factor affecting the wheel-rail force is the short wave track irregularity. The paper studies irregularity with simulation model and dynamic response in different working conditions by analyzing the data of the shortwave irregularity. Comparing and analyzing the dynamic responses may help to know more about safety and stability of the train. The final analysis may provide theoretical guidance for controlling the irregularity in the railway maintenance and some advice for the controlling the shortwave track irregularity. |
