The asymmetric rotor and the rub-impact behavior are important sources of instability and may cause severe vibrations.
However, the dynamics of the rotor-bearing system simultaneously considering the two factors has not gained sufficient attention in available investigations.
In this paper, the steady-state response and stability of an asymmetric rotor with rub-impact were evaluated.
The asymmetric rotor was modeled by beam elements with asymmetric cross section, and the nonlinear equations of motion were established in the rotating frame.
The multiharmonic balance (MHB) method was employed to obtain the linearized form of the nonlinear equations of motion.
Either the asymmetry of rotor or rub-impact can result in instability and make the problem difficult to solve.
Thus, the arc-length method was utilized to trace the branch of the solutions.
In order to improve the calculation speed and accurately predict the solution, the alternating frequency/time domain (AFT) was adopted to calculate the iteration of the arc-length method.
Based on the proposed method, the effects of stator stiffness, gap size, unbalance, and asymmetric in shaft on the steady-state response and stability were obtained.
