| 摘 要： | 针对弹簧浮置板轨道的不同过渡段形式建立有限元模型,采用移动轮对荷载进行动力仿真计算.分析不同过渡形式下钢轨的动力特性,包括动态的钢轨位移、钢轨挠度变化率以及钢轨加速度.计算结果表明,采用弹性支承块和加密浮置板弹性支座相结合的方式能使钢轨动态位移变化更为平缓,适当增加加密的弹簧支座数量也有利于过渡段钢轨的动态平顺性.

| Abstract: | Different finite element models for different types of spring floating slab transition sections have been built.The moving loads of wheel set are used to analyse the dynamic performance of rail in transition section.The designs of trasition section are evaluated by the dynamic displacement of rail,the change ratio of rail deflection and the acceleration of rail.The results suggest that the design shall use both elastic supporting block and spacing deduced spring to smooth the dynamic change of rail displace... |
