建立了与限位器碰摩的转子动力学方程 ,用数值积分方法得到了碰摩非线性动力响应。分析中考虑了陀螺效应 ,采用分段线弹性和库仑摩擦模型描述碰摩力。研究双频进动、局部碰摩、拟整圈碰摩和整圈碰摩的振动特征。讨论了不平衡量和激振力幅度变化对碰摩振动形式和特征的影响 ,并给出碰摩振动试验结果 ,以验证数值分析结论。 The rotor dynamic equation of the friction with the stopper is established, and the nonlinear dynamic response of the friction is obtained by numerical integral method. The gyroscopic effect was considered in the analysis, and the piecewise linear elasticity and Coulomb friction model were used to describe the rubbing force. The vibration characteristics of dual-frequency precession, local rubbing, quasi-full-circle rubbing and full-ring rubbing are studied. The influence of unbalance and the variation of the amplitude of the exciting force on the vibrational modes and characteristics of the rubbing is discussed. The results of the rubbing vibration test are also given to verify the numerical analysis.
