| 摘 要： | 通过监测CRH5动车组齿轮箱振动,计算万向轴特征频率能量对评估万向轴状态具有现实意义.本文简述了经验模态分解(EMD)的基本方法,对实测200km/h下齿轮箱振动信号进行EMD分解,提取万向轴特征频率成分,并计算其能量.研究结果标明该方法可以有效对万向轴动不平衡进行评估.

| Abstract: | Calculate CRH5 cardan characteristic frequency energy by monitoring the vibration of gearbox is meaningful to assess the state of the cardan shaft .This paper described the EMD method used to decompose the signal of gearbox vibration when the speed of train is 200km/h, extract characteristic frequency of the cardan shaft and calculate the energy .Research results show this method can evaluate the unbalance of cardan shaft ef-fectively. |
