| 摘 要： | 转子系统的主共振型双稳态特性主要包括双稳态开始及结束时的转速ωbd,ωba,双稳态转速区ωbd～ωba、转子系统振幅及相位角的变化规律。选用在试验中曾多次出现过双稳态的模型转子作为理论分析原始数据,在较宽的系统参数的范围内,进行转子系统主共振型双稳态特性分析。

| Abstract: | Based on theoretical analyses and experiments of flexible rotor squeeze film damper system with centralizing springs,this paper presents the investigation of the main resonant bistable operation occurred near the main resonant speed of the system,and deals with the regularity of occurence of the bistable operation and the influence of system parameters on the behaviors of the bistable operation.The calculated results and the experimental data are in a good agreement.It is found that the main resonant bistable operation is characterized by the sudden change of rotor vibration amplitude and by the transposition disc mass center.The reasons of the difference between theoretical analyses and experiments are discussed. |
