The friction noise of water lubricated bearing system is analyzed by using ABAQUS software.By using the analysis method of finite element complex eigenvalue and based on the positive or negative of complex eignvalue real part

the possility of bearing system generating noise can be estimated.If the real part eignvalue is positive

the noise will generte.The influence of water lubricated bearing structure

including the size of transition radius

groove radius

the number of groove and the rubber thickness on friction noise is studied.The result shows that all of them has great influence on the friction noise of water lubricated bearing.
