| 摘 要： | 0引言目前,客运专线铁路轨道结构主要有两种类型:有碴轨道和无碴轨道。有碴轨道在高速列车载荷的反复作用下,残余变形积累很快,而且沿线路方向的变形积累和轨道刚度分布不均匀,从而造成轨道不平顺,影响列车运行的舒适性和安全性,同时显著增加轨道的养护维修工作量,加大铁路的运

| Abstract: | In this article the principle of the total potential energy being constant of the elastic system dynamics and the method of 'take one's seat according to the number on the ticket" in forming the matrix are used to establish 22 free degree Burger slab track units,and the finite element method is also employed to analyze the characteristics of the vertical natural vibration of the track and the influence of the track's structural parameters on the natural frequency. |
