摘　　要：以6201轴承为研究对象建立一个4自由度的动力学模型。利用MATLAB和Runge-Kutta方法求解深沟球轴承的位移、速度及加速度的振动特性。通过计算滚动体通过外圈的频率理论计算值与模型的仿真值可知,理论计算值与仿真值具有较好的一致性。通过测振仪测量深沟球轴承的振动加速度值,测量值与仿真值相一致;利用此测量模型,进行研究磨损后径向游隙和波纹度对轴承振动的影响,结果表明,此方法是一种研究轴承振动非常有效的方法。Taking 6201 bearing as the research object,a dynamic model of 4 degrees of freedom is established. to solve the vibration characteristics of the displacement,velocity and acceleration of deep groove ball bearings by MATLAB and Runge-Kutta method. By calculating the theoretical value of the frequency of the rolling element passing through the outer ring and the simulation value of the model,it can be known that the theoretical calculation value and the simulation value have good consistency. Through experiments to verify the measured values and simulation valuesare consistent. According to this mathematical model,the effect of radial clearance and waviness on bearing vibration after wear is studied. The results show that this method is a very effective method to study bearing vibration.
