对带不平衡量的Jeffcott转子,采用当量弹簧线性碰摩模型,进行了同步全周碰摩运动分析:寻找同步全周碰摩解的参数存在区,求出同步全周碰摩解的表达式,讨论同步全周碰摩解的稳定性,导出同步全周碰摩解稳定性判据,给出稳定区判据近似表达式.
For an unbalanced Jeffcott rotor, an equivalent spring linear rub-impact model was used to analyze the full-range rub-impact motion simultaneously: finding the parameters of the full-range rub-in-motion solution and obtaining the expression of the full- The stability of the simultaneous rubric solution during the whole week is discussed, and the criterion of stability of simultaneous rubric solution is deduced. The approximate expression of the criterion of stable area is given.
