摘要
本文用车辆－轨道系统耦合动力学的理论，分析了轨道扭曲不平顺的幅值对车辆动力学性能的影响，并以《铁道车辆动力学性能评定办法和试验鉴定规范》中规定的第二限度（安全限度）为评定准则，提出了轨道扭曲不平顺的安全限值，并对其临时补修标准作出了评价。
The influence of trark torsion irregularigy to the dynamic behaviour of vehicle is studied with the theory of track-vehicle coupling dynamics.Based on the calculation results and GB5599-85,the safety limit of track torsion irregularity is proposed, At last , the recommendation for urgent repair standard of track torsion irregularity in Rules of Maintenance of Way is assessed.
