The non-linear rub-impact model based on Hertz contact theory is used to study the rub-impact fault phenomenon of multi-disk rotor system in engineering. The research results help to better grasp the vibration characteristics of multi-disc rubbing rotors and provide a theoretical basis for more accurate diagnosis of rotor rub failure and improvement of the dynamic characteristics of the rotor system.
