摘要
在对有限长滑动轴承非线性压力分布函数及油膜力分析的基础上,定义了4个轴承流固耦合作用特征系数,同时根据轴承流固耦合运动能量转化的载荷平衡方程,提出了油膜-转子系统中轴承运行失稳的判据方程,解释了油膜力的作用机理,根据实例给出了轴承失稳的动力学特征。
Based on the analysis of the oil film force of a journal bearing, four characteristic coefficients of the journal bearing are derived. Moreover, according to fluid-structure-interaction equilibrium equations, a stability criterion equation of the oil film-rotor system is presented, which can explain the acting mechanism of the oil film force on the rotor. The dynamic destabilization characteristics of the journal bearing are given by testing on the work set. Figs 6 and refs 6
