摘　　要：高速铁路列车运行时的安全性、舒适度以及轮轨动力特性与缓和曲线的线型、长度具有较高的相关度。采用动力学分析软件SIMPACK建立高速铁路车线系统模型,在考虑高速铁路存在轨面不平顺的情况下,引入低干扰谱,研究缓和曲线线型及长度对高速列车运行时各主要评价指标的影响。研究表明,对于300 km/h以上的高速列车,当曲线半径达到7 000 m及以上,缓和曲线达到一定长度时,采用三次抛物线型缓和曲线与半波正弦型相比差别不大,均能满足行车安全需求。The safety, comfort and wheel rail dynamic characteristics of high-speed railway train running are highly correlated with the line shape and length of the transition curve. The high-speed railway train-line system model was built by dynamic analysis software SIMPACK. Considering the rail surface irregularity of high-speed railway, the low interference spectrum was introduced to study the infuence of the line shape and transition curve length on main evaluation indexes when the high-speed train was moving. The research shows that when the curve radius of reaches 7000m or more and the transition curve reaches a certain length, the three parabola type transition curve has little diference compared with the half wave sine type for the high speed train above 300 km/h.
