摘要
通过求解考虑油膜惯性力转子－挤压油膜阻尼器系统的微分方程，得到了系统稳态圆响应的频响特性曲线、骨架曲线和传递率曲线，并比较了油膜惯性力对于系统稳态响应的影响。分析证明：油膜惯性力使系统的等效刚度系数与阻尼系数产生较大的变化，并使系统的共振峰值得到抑制，系统参数对稳态响应有较大的影响。
In this paper the amplitude frequency characteristics, bone plot and transmission ratio of steady state circle responses are studied and the influnce of film inertia is investigated.It is found that the equivalent stiffness and damp coefficients change and the amplitude at critical rotating decrease when the film inertia is considered.Various system parameters have great impact on steady state responses. It is concluded that the effect of film inertia must be included when we analyse the dynamics of rotor SFD system.
