随着高速铁路和城市轨道交通的快速发展,对这些交通工具的耐碰撞性要求也越来越高并取得了很大的发展。但是在普通铁路线上运行的客运和货运牵引机车才开始进行相关研究,国内还没有相关的标准。文中介绍了出口新西兰机车耐碰撞性设计,通过有限元计算分析方法,对机车耐碰撞性进行了分析校核。 With the rapid development of high-speed railway and urban rail transit, the collision resistance requirements of these vehicles are also getting higher and higher and great progress has been made. However, the passenger and cargo traction locomotives operating on the ordinary railway line have just begun to carry out relevant research, and there is no relevant standard in China. This paper introduces the design of crashworthiness of locomotives exported to New Zealand and analyzes the crashworthiness of the locomotive by finite element method.
