| 摘 要： | 浮置板轨道结构在城市轨道交通中的减振降噪效果最显著,而其减振性能与它的固有频率有关.通过建立浮置板轨道有限元分析模型,对浮置板轨道进行了模态分析.分析了浮置板轨道的断面形状、弹性支座刚度、浮置板长度、弹性支座布置间距等对浮置板轨道系统振动频率的影响.分析结果可为浮置板轨道结构的优化隔振设计提供一定的理论依据.

| Abstract: | The effect of floating slab track in urban mass transit to reduce vibration and noise is very obvious and its capbility of reducing vibration is related with its inherent frequecy. This paper builds up an element model of floating slab track to analyze its normal models,the influence of the section configuration, support pad stiffness, the length and support pad spacing length of floating slab on vibration frequency of this system. It would provide a theoretical basis to reduce the vibration of floating slab track as thes hold. |
