摘要

航空发动机双转子系统不对中会导致振动异常增大，进而发生转静碰摩，影响转子安全稳定运行。以双转子系统为研究对象，考虑轴承不对中-联轴器不对中-碰摩故障，基于集中质量法建立转子系统动力学模型，根据拉格朗日方程建立系统运动微分方程，采用Range-Kutta法对其进行求解，研究转速、不对中角度、联轴器不对中量等关键参数对系统非线性动力学特性的影响机制。研究结果表明，随着转子转速增大，系统呈现出周期、多周期、拟周期、混沌运动等复杂的动力学特性，且转速在1 500~2 200 rad/s时，系统通过多次阵发性分岔和阵发性倒分岔在周期2运动和混沌状态之间切换；振动响应随联轴器平行不对中量变化的分岔图中存在“跳跃”等非线性现象；随着轴承不对中角度的增大，高转速的混沌区间缩小，稳定的周期运动区间增大。

Abstract

The misalignment of the dual-rotor system for the aero-engine will lead to abnormal increase of the vibration which results in the rotor-stator rubbing and affects the safty and stability of the rotor operation.The dual-rotor system was taken as the research object.Considering the combination misalignment-rubbing fault

the dynamic model of the rotor system is established based on the lumped mass method.The differential equation of the system motion was established according to the Lagrange equation

and the Range-Kutta method was used to solve it.The influence mechanism of the key parameters such as the speed

the misalignment angle and the coupling misalignment on the nonlinear dynamic characteristics of the system was studied.The results show that the system presents complex dynamic characteristics such as periodic

multi-periodic

quasi-periodic and chaotic motion with the increase of the rotor’s speed.When the speed is in the range of 1 500-2 200 rad/s

the system switches between periodic 2 motion and chaotic state through multiple paroxysmal bifurcations and paroxysmal inverted bifurcations.There are nonlinear phenomena such as jump in the bifurcation diagram of the vibration response with the change of the parallel misalignment of the coupling.As the misalignment angle of the bearing increases

the chaotic interval of the high speed decreases

and the stable periodic motion interval increases.
