移动荷载作用下桥上无砟轨道动力分析

桥上无砟轨道越来越多地应用于高速铁路.目前,桥上无砟轨道结构动力计算理论还不够完善,现采用有限元方法,把移动荷载和轨道结构以及桥梁看成一个系统,对板式无砟轨道在移动荷载作用下的动力性能进行分析,并通过MATLAB编程实现,计算结果符合无砟轨道结构和桥梁基本原理.

Dynamic analysis of ballastless track on bridge subjected to moving load

Ballastless track on the bridge was increasingly used in high-speed railway. At present, the theoretical calculation of the ballastless track on the bridge was not enough to analysis the dynamic performance, the finite element method was used to analysis the dynamic performance of the system of slab track and bridge. And through MATLAB, the results were in line with the basic principles of the ballastless track and bridge.
