根据转子动力学理论
建立了柔性转子-轴承系统的力学模型及非线性动力学方程.将W ilson-θ法改进
并结合预估-校正机理和N ew ton-R aphson法
得到一种有效的求解动力学系统不平衡响应的方法
以柔性转子圆盘处的质量为控制参数
运用该方法来求解转子系统的不平衡响应.数值结果揭示了系统具有周期运动、准周期运动、五周期运动、跳跃等非线性现象.
Dynamic model of a nonlinear flexible rotor-bearing system was established based on rotor dynamics.A method consisting of improved Wilson-θ 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.
