Rub-impact fault model for dual-rotor system was further developed, in which rubbing board is regarded as elastic sheet.
Sheet elastic deformation, contact penetration, and elastic damping support during rubbing of sheet and wheel disk were considered.
Collision force and friction were calculated by utilizing Hertz contact theory and Coulomb model and introducing nonlinear spring damping model and friction coefficient.
Then kinetic differential equations of rub-impact under dry rubbing condition were established.
Based on one-dimensional finite element model of dual-rotor system, dynamic transient response of overall structure under rub-impact existing between rotor wheel and sheet was obtained.
Meanwhile, fault dynamic characteristics and impact of rubbing clearance on rotor vibration were analyzed.
The results show that, during the process of rub-impact, the spectrums of rotor vibration are complicated and multiple combined frequency components of inner and outer rotor fundamental frequencies are typical characteristic of rub-impact fault for dual-rotor system.
It also can be seen from rotor vibration response that the rubbing rotor’s fundamental frequency is modulated by normal rotor double frequency.
