【摘要】 基于 Fokker-Planck 接触振动方程,用完全数值解法研究了表面波纹度对滚动轴承振动的影响,分析了接触位移、接触振动速度、加速度随工况参数的变化。结果表明,对于表面波纹度引起的接触振动,轴承振动速度型检测与加速度型检测具有相同的效果；接触载荷越高,表面波纹度引起的接触振动越剧烈；圆周方向上波纹度的波数、转速对接触振动参数影响显著,但波纹度的幅值在小于5μm 时,波纹度幅值对接触振动影响不显著。更多还原

【Abstract】 The elastic vibration described with Fokker-Planck equation was studied with full numerical method,and the effects of waviness parameters,rotation speed,normal load etc on the displacement,velocity and acceleration of contact vibration were studied.The calculated results demonstrate that the velocity method and the acceleration method are same effective in measuring rolling bearing vibration; that the higher the contact load,the severe the contact vibration;that the waviness number in the circumferential direction and shaft rotation speed have significant effects on vibration parameters;and that the waviness amplitude in the engineering practice of rolling bearings does not influence the contact vibration evidently.更多还原
