Spectrum peaks were found in the lower frequency area of the vibration signals obtained from the compressor set. 摘要分析某压缩机组振动信号的频谱发现低频处具有较高的谱峰。
The proposed UWT effectively extracted the friction fault features of amplitude modulation and transient impact from vibration signal of a gearbox. 采用这种非抽样小波变换从齿轮箱的振动信号中有效提取幅值调制和瞬态冲击的摩擦故障特征。
