Abstract横风作用下的列车安全运行速度限值应通过列车气动特性和车辆轨道动力学特性的分析得到。以我国CRH3型高速列车实车为原型,考虑真实受电弓、转向架等列车的细部特征,假定列车在平地上行驶,对列车速度分别为200、250、300、350和380km/h,横风速度分别为10、15、20、25和30m/s,风向角为90°的25个工况进行气动特性的数值模拟,并采用国内实测轨道谱和德国轨道谱分别对这25个工况的车辆轨道动力学性能进行仿真计算和对比分析。结合国家标准和技术规范,给出CRH3型列车在平地上运行时,横风风速与列车最大安全运行速度之间的对应关系,为横风作用下的列车运行安全控制提供参考。
Other AbstractThe limited safe speed of a high-speed train under crosswind should be obtained by analyzing the aerodynamic and vehicle-track dynamic characteristics. A real high-speed train of Type CRH3 was taken for case study. The train was assumed to run on a plane area under 25 numerically simulated operating conditions when the train speeds were chosen as 200, 250, 300, 350 and 380 km/h, the crosswind velocities as 10, 15, 20, 25 and 30 m/s and the wind direction angle as 90°. The detailed characteristics of real bogies and pantographs and so on were taken into account. The dynamic vehicle-track charateristics corresponding to the above 25 operating conditions were calculated respectively and compared in line with the domestic measured track spectra and the German track spectra. In accordance with the National standards and technical specifications concerned, the relationship between the crosswind velocity and the maximum safe operating speed of the CRH3 train running on a plane area was found. The results will play a guiding role in control of safe operation of a train under crosswind.
