摘　　要：利用动力仿真软件计算多种类型轨道单一不平顺、复合不平顺激扰下高速客车的动力响应,着重分析了轨道曲线头尾处直缓点和圆缓点区域的复合不平顺对高速客车运行安全性和平稳性的影响,研究结果表明,轨向和水平逆相位复合不平顺类型对列车运行的安全性和平稳性有很大的影响,尤其在曲率变化的区域内需要重点控制。The dynamic response of high speed coach of various type track under single unsmooth and composite unsmooth situation were calculated with dynamic simulation software. The composite unsmooth of track curve head-tail connecting points of straight lines and transition point area influences on the high speed coach running safety and stationary were emphasis analyzed. The research results indicated that the track and horizontal contra-relationship composite unsmooth had large influences on coach running safety and stationary, especially the focal control need in curvature changed area.
