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,通过对路涵过渡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,对京秦既有线路涵过渡段提速到200km/h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。
In connection with the increasing speed and the renovation of the JingQin Railway Line,the dynamic computer simulation of the vehiclesubgrade is performed. Under the condition of different speed and the condition of strengthening or no strengthening of road culvert approach sections,the safety and comfort index of the vehicle and the main dynamic characters of track and road culvert approach section are analyzed. Based on the above results,the corresponding evaluation and suggestion are proposed concerned with whether the existing road culvert approach section and the feasibility of strengthening design are suitable to increasing speed of 200km/h. The results of the calculation are compared with the test results of vehicle. The reliability of the simulation analysis is proved by the test results.
