| 摘 要： | 本文给出了非线性挤压油膜阻尼器柔性转子系统试验中得到的发生在转子系统临界转速附近的主共振型双稳态跳跃的一般特性,并讨论了系统参数对其特性的影响。研究表明,主共振型双稳态跳跃以转子振幅发生突变、盘处的质心发生转向为特征。

| Abstract: | The behaviors of main resonant bistable jump occurred in experiments of non-linear squeeze film damper with retainer springs-flexible rotor system and thenearly main resonant speed of a rotor system are presented in this paper.The in-fluence of system parameters (such as radial clearance ratio,unbalance,retainerspring stiffness) on the bistable behavior is studied.It is shown that the mainresonant bistable jump is characterized by the sudden change of rotor vibrationamplitude and by the transposition disc mass center. |
