摘　　要：根据非线性力学和声辐射理论,建立滚动轴承表面的波纹度模型、振动模型和波纹度激励下的非线性噪声模型。对6204轴承进行Matlab仿真分析,得出波纹度及其波数、幅值等参数变化对滚动轴承噪声声压级影响的规律。对今后的生产、加工具有实际指导意义。Based on the nonlinear mechanics and acoustic radiation theory, nonlinear noise model waviness model rolling bearing surface waviness vibration model and excitation. The 6204 bearing were analyzed on the Matlab. The influences of the main parameters waviness, regular wave number and amplitude of the wave and other parameters on the rolling noise level impacts were obtained. It has practical guiding significance to the production and processing in the future.
