摘　　要：为得到谐波减速器在不同振动状态的特征信息,应用“特征?能量”的理论和小波包变换的方法对XB-80-134H型谐波减速器的振动信号进行分析,得到不同振动状态的能量向量,即以信号各个频段振动能量密度值的组合作为能量向量,应用这些能量向量为谐波减速器的故障诊断提供了新的解决方法。In order to get the vibration information of harmonic reducer, character - - energy theory and wavelet package method were applied to the modal XB - 80 - 134H harmonic reducer. The character en- ergy vectors that are the combination of energy density of some frequency segment were obtained. A new method was applied to identify the failure of machine by using these energy vectors.
