Application of Demodulated Resonance Technique Based on Blind Source Separation to Gear Contact Diagnosis

Yao Xiaoshan1) Zhang Yongxiang1) Ming Tingtao1) Wang Xinhai2) (College of Naval Architecture and Power,Naval University of Engineering,Wuhan 430033)1) (Naval Agency in Factory 431,Huludao 125004)2)  
A method using demodulated resonance technique based on blind source separation is developed for gear contact diagnosis.Using blind source separation,pure fault source signal is obtained by separatin g mixed signals from sensors.Applying demodulated resonance technique to separated signals,gear contact character information is extracted successfully.
