摘要
建立连续的三维钢弹簧浮置板轨道结构的动力传递特性有限元分析模型,针对不同设计参数和激振频率,研究该轨道结构的动力传递特性和隔振效率。计算结果表明,所采用的方法可详细解剖浮置板相关设计参数对隔振效率的影响。
A continuous 3 D finite element model for steel-spring floating slab track （FST） analysis is established. The dynamic transfer characteristics and the isolation effect of this kind of track structure are studied for different design parameters and actuation frequency. Computation results show that this method can be used to study the influence of the design parameters on the vibration isolation effect. It al- so provides a theoretical evidence for optimization design and domesticating of the steel-spring FST structures.
