摘要
提出了运用随机减量法从轮对随机响应中提取自由响应 ,识别出模态参数的方法 ;该文以锥型踏面和磨耗型踏面为例进行了分析 ,并提出了在等效斜度变化的磨耗型踏面情况下随机减量函数的提取方法。计算结果表明 。
The study on time domain of wheelsets parameters is carried out about lateral vibration of locomotive and vehicle, freedom response is got from random response by random decrement technique and then modal parameters are identified also. Constant conicity and unconstant conicity are researched respectively, and the way of getting random decrement function is analysed. The results is good by compute, having high accuracy.
