Spectrum Analysis and Its Application to Gearbox Fault Diagnosis

Li Xiaohu Jia Minping Xu Feiyun (Department of Mechanical Engineering, Southeast University Nanjing, 210096, China)  
Based on the analysis of the vibration of gear boxes and the forming mechanism of modulation sibeband, a method combining spectrum average and cepstrum analysis is proposed to analyze the characters of the output signal of a monitoring system in the frequency domain for detecting the fault of gear boxes along with its cause. Testing results have shown the effectiveness of the method proposed in the paper.
