摘要
Abstract
Dynamic model of a nonlinear flexible rotor-bearing system was established based on rotor dynamics. A method consisting of improved Wilson-0 method, the predictor-corrector mechanism and Newton-Raphson method was proposed to determine unbalanced response of dynamics system. By taking the disc mass as the control parameter, nonlinear dynamic responses of rotor system were obtained by the proposed method. Numerical results reveal the nonlinear characteristics such as periodic, quasi-periodic, 5-periodic, jump solution.关键词
