摘要
结合中介轴承故障特征公式,采用小波分析技术对内、外圈同向和反向旋转的中介轴承进行特征提取,通过对某型双转子航空发动机机匣的振动信号进行分析,验证该方法的有效性。
According to fault feature formula of intershaft bearing,the wavelet analysis technology is used to extract the feature of intershaft bearing with inner and outer ring rotating in opposite and same direction. The vibration signals are analyzed for casing of a certain type of dual-rotor aero-engine,and the effectiveness of the method is verified.
