摘要

摘要: 从地铁轮轨之间的相互作用分析了激振源以及激振力表达模型和施加方式,在阐述浮置板轨道隔振原理、分析橡胶支承浮置板和钢弹簧支承浮置板基本结构的基础上,剖析了基于集总参数模型、连续弹性支承模型、连续弹性点支承模型的浮置板轨道隔振系统动力学建模方法。从动力学性能、模态分析、隔振性能3个方面阐明了浮置板轨道的动态响应性能。针对浮置板轨道隔振存在的主要问题,指出基于可调刚度、阻尼的隔振器参数优化与(半)主动隔振控制技术是其发展的方向。

Abstract: The excitation induced by the interactions of wheels and subway tracks was discussed.Also,its models and applied methods were depicted.After the introducing of the principle of isolation for floating slab track(FST) and displaying of the structures of FST supported with elastomer and spring,the models of FST,including lumped parameter model,continuous model and discrete model,were demonstrated.Then the dynamic performance,modal analysis and effectiveness of isolation for FST were showed.In order to solve the main isolation problems of FST,the parameter optimization for stiffness and damping constant as well as the semi-active vibration isolation technology or active vibration isolation technology were considered to be the development trend.
