摘　　要：基于Hertz接触理论,提出了5自由度3D轴承模型在转速、摩擦、离心力和陀螺力矩作用下进行接触时的动力学分析方法。建立了轴承接触动力学模型,利用数值积分和数值仿真方法对其进行了时变位移和接触力振动分析。结果表明,考虑影响轴承振动位移的时变因素所获得的计算结果比用传统的轴承结合部等效参数计算结果要大,该方法有效地解决了轴承转速、摩擦等时变因素影响下的时变位移等问题。Basod on Hertz contact theory,a new dynamic analysis method is put forward for 5 -freedom and 3D angular contact ball bearing model considering the effect of friction,centrifugal force and gyroscope torque. The contact dynamic model of angular ball bearing was proposed,and the method of numerical integral and numerical simulation is applied to research the vibration analysis of time - varying contact stiffness,contact force and time - varying displacement. The resuits revealed that displacement with time - varying factors is more greater than that calculated by traditional equivalent method of jolnts＇parameters,and the new method is useful to deal with time - varying displacement of bailing bearing with the effect of time - varying factors such as speed and friction.
