摘要：Due to the existence of Duffing-type nonlinearity, Hertzian contact and bearing clearance, the dynamic characteristics of rub-impact rotor system are seriously affected. The paper presents a new kinematic equation in plural form for the typical rotor system by employing the Lagrange equation, which consists of a disk fixed on a shaft of Duffing-type nonlinearity, a stator of Hertz contact force and Coulomb friction. Furthermore, based on the complex harmonic balance method, the analytical frequencies of this nonlinear rotor system under unperturbed and perturbed rotating cases are comprehensive developed, respectively. Numerical simulations of the Runge–Kutta method were conducted to verify the analytical results. The comparison showed that out of the resonant range, the theoretical and numerical results were in good agreement. © 2019 Elsevier Ltd
