Abstract

Abstract

The bistable state occurrence has been investigated theoretically for squeeze film damper(SFD) supported flexible rotor system.The bistable state calculation method of the system is presented in detail.The bearing parameter B ,stiffness ratio f and unbalance U are chosen to analyze the bistable state performance,and a domain of U(B,f ) is obtained.The results show that the bistable state phenomenon can be avoided as long as the value of U beyond the above mentioned domain.This makes it convenient to optimize the SFD design parameters.
