| 摘 要： | 本文从刚性转子——SFD(Squeeze Film Damper,即挤压油膜阻尼器)系统的频响方程出发,求得了系统频响曲线的骨架曲线和共振振幅轨迹线;分析了产生双稳态的原因及系统参数对跳跃的影响。发现双稳态跳跃的非线特性为Duffing型非线性与附加分岐型非线性及两者的组合。

| Abstract: | According to vibration frequence responsing formulas, reduced the framework curve and the boundary curve of the roots of the frequence responsing formulas, analysed the cause of the bistable operation inducation and influences of the system parameters to jumping. The study showed that the system nonlinear characteristic would appear as Dufring type, the bifurcated type and their composition. |
