| 摘 要： | 为研究弹性支承块式无砟轨道的动力特性,运用动力学基本原理，分析了扣件刚度、块下胶垫刚度与阻尼不同匹配以及轨枕块质量对基础受力的影响。结果表明:在满足轨道整体刚度时，扣件和枕下胶垫应尽量采用较小刚度值；对于不同激振频率段，应分别对待扣件和枕下胶垫阻尼取值；弹性支承块质量也如此。

| Abstract: | In order to study the dynamic characteristics of elastic bearing block ballastless track,the paper analyzes the different matching between fastener rigidity,rubber pad rigidity and damping as well as influence of sleeper quality on foundation stress with the basic principle of dynamics.It is indicated that when track overall rigidity is satisfied,fastener and rubber pad shall be of as less rigid value as possible.For the sections with different excited frequency,the fastener and rubber pad shall be separately valued,and so is the quality of elastic bearing block. |
