| 摘 要： | 针对现有的预制短板浮置板轨道结构以及普通轨道结构各自在实际工程应用中的各种参数建立三维有限元模型.通过大型有限元软件ANSYS对其在不同预制长度的条件下做落轴冲击的仿真分析,分别得到各自结构的动态响应,而后再做以比较,提出在不同工况的条件下合理的选型、应用以及搭配方案,并为预制浮置板轨道的其他动力性能的研究提供了一个关键的动态理论参数.

| Abstract: | According to the existing prefabricated floating slab track, common rail and their practical en- gineering parameters, 3 -d finite element models were set up. Simulation analysis was done on different length under the conditions of the wheel load drop impact using the finite element software ANSYS. Their dynamic re- sponse was determined and compared with different driving conditions. The reasonable selection of different con- ditions, application and collocation program were put forward. And a critical dynamic theory parameter for the other dynamic characteristics of Prefabricated Floating slab Track was provided. |
