针对舰船电机轴承故障诊断技术难点，采用基于振动加速度共振解调频谱分析方法，通过不同程度外圈故障的对比实验，验证以振动加速度峭度系数和振动速度有效值为指标，可以提高异步电动机轴承故障诊断的有效性。
Aiming at the technical difficulties of motor bearing fault diagnosis, using resonant demodulated spectrum analysis in frequency domain of vibration acceleration, bearing outer race fault comparison tset with different severity, verify the effectiveness indicators of kurtosis for vibration acceleration and root mean square of vibration velocity, and improve the diagnosic effectiveness of bearing fault in induction motors.
