Dynamic Response of Double-disk Rotor with Squeezed Oil-film Dampers and Optimization of Its Supports
摘要
Abstract
The dynamical response of a low-pressure rotor in an aero-engine and the optimization of its supports were investigated. Based on the model of the low-pressure rotor, a dynamically simplified model of a double-disk rotor with squeezed oil-film dampers (SFD) at both ends was established. Its kinetic equations were derived. The numerical method was applied to solve these differential equations and the responses of the rotor were obtained. To reduce the vibration of the rotor, the stiffness of the elastic supports of the rotor needed to be optimized. The Multi-Island Genetic Algorithm and Sequential Quadratic Programming were applied to realize the multi-objective optimization and the best stiffness of the two supports was obtained.关键词
