摘　　要：结合京秦线提速改造工程进行了列车-路基动力仿真计算。在不同速度条件下,通过路基段加固前后状态下机车车辆运行安全舒适性指标、轨道及路基主要动力性能指标的分析计算,在此基础上对京秦既有线路基对时速200km/h提速的适应性及加固方案的可行性提出了相应评价意见与建议,并与随后的实车试验进行了对比。试验测试结果验证了仿真分析的可靠性。Aiming at the speed enhancement and remoulding engineering of Jingqin Railway Line, a dynamic computer simulation of the vehicle-subgrade system is performed. Under various speed and strengthening conditions of subgrade, the safety, comfort index of the vehicle and the main dynamic characters of track and subrade are analyzed. Comments and advice are given. The suitability of the current subgrade to increasing speed to 200km/h and the feasibility of strengthening design are addressed. The results of the calculation are compared with the test results of vehicle. The reliability of the simulation analysis is verified by the test results.
