弹性扣件轨道减振改造措施的动力性能分析

Dynamic performance analysis on the reform measure of elastic fastener track structure

通过采用不同刚度的扣件以及建立基于钢轨调谐质量系统的弹性扣件轨道模型,在钢轨上"线"式和"面"式铺设调谐质量块,并进行动力性能的分析,结果表明:在扣件刚度一定时,弹性扣件轨道结构从"线"式到"面"式,钢轨位移和扣件支反力会逐渐减小。

Set up the ＂line＂ and ＂surface＂ model based on rail Tuned Mass Damper system, and carry on the dynamic performance analysis. The results show that： when the fastener stiffness is constant, from the ＂line＂ and to ＂surface＂, the rail displacement and fastener reaction of elastic fastener track will decrease gradually.
