高速磁浮列车车体国产化

Chinese domestic components of high-speed maglev train body

分析了由德国进口的上海磁浮列车车体结构静力学性能,结合中国铝合金挤压型材的生产工艺水平,提出了大型整体铝合金挤压型材拼装的磁浮列车车体设计方案。根据磁浮列车空气动力性能研究结果,参照轮轨系统列车车体结构设计规范,分析了作用于高速磁浮列车车体结构上的八种载荷组合工况。对两种车体结构静力分析结果的比较表明车体应力与振动频率均满足规范要求,车体实现国产化是可行的。

Structure static analysis of Shanghai maglev train body imported from Germany was carried. Combined with the manufacture technology level of aluminum alloy profiled extrusion material, maglev train body made up of the large-type integral aluminum alloy extrusion material was put forward. Based on the research result of its aerodynamic performances, the eight loads series acted on high-speed maglev train body were made sure refers to the design rules of wheel-rail system car body configuration. Static analysis results of two car bodies show that carbody stress and frequencies satisfy design demands, it is feasible that maglev train body can be made in China.
