    《Method and Device for Identifying Natural Frequency of Track Fastener System》

    Patent description:本发明属于轮轨交通系统轨道结构动力学设计领域,涉及一种轨道扣件系统共振频率的识别方法及装置。将需要识别的外界激振频率作为输入频率;根据所述输入频率对应的频变动参数获得扣件系统第一有限元模型;根据第一有限元模型获得所有位于所述轨道上车轮在各个扣件节点的等效质量;根据所述输入频率对应的频变动参数和获得的所有位于所述轨道上的车轮在各个扣件节点的等效质量获得扣件系统第二有限元模型;根据第二有限元模型获得轨道扣件系统多阶固有频率;当所述多阶固有频率与所述输入频率满足预设条件,则输入频率为共振频率。
