摘 要: 利用ABAQUS软件建立平板型水润滑轴承的摩擦噪声分析模型,采用复模态理论,依据复特征值实部的正负判断轴承系统发生噪声的可能性,如果有实部为正的特征值,则可判断系统有发生噪声的可能性。通过有限元分析,获得了轴承系统在不同参数下的失稳倾向,其中包括摩擦系数、水槽半径大小及水槽形状。分析结果表明:摩擦系数对轴承系统摩擦噪声的影响最大,水槽圆弧半径和形状对噪声预测结果也有一定影响。
关 键 词: 机械摩擦、磨损及润滑;水润滑轴承;有限元;摩擦噪声

Abstract: Friction noise analysis model of plate type of water-lubricated bearing was built using ABAQUS software. By using the analysis method of finite element complex eigenvalue theory and based on the positive or negative of complex eigenvalue real part, the possibility of bearing system generating noise were estimated. If the real part eigenvalue was positive, the noises would be generated. Through the analysis of finite element, unstable tendency of the bearing system under different parameters was obtained, including the friction coefficient, groove radius and shape. The results showed that the friction coefficient had great influence on the friction noise of water-lubricated bearing. Groove radius and shape also had a certain impact on noise prediction results.
Key words: mechanical friction, wear and lubrication; water-lubricated rubber bearing; finite element; friction-induced noise
