摘要：

The rub-impact of rotor-stator system occurs when the relative motion gap between the blades and the casing exceeds radius clearance during the operation of aero-engine. It is great significant to study the temperature variations during the rub-impact of rotor-stator system for preventing combustion. The effects of nonlinear contact, centrifugal force, normal acceleration are considered to model the rub-impact contact forces of a rotor- stator system based on Hertz contact theory. The temperature field of the rub-impact of the rotor-stator system is calculated using the finite difference method by considering frictional heat generation, heat distribution, and heat conduction. Meanwhile, a rotor-stator rubbing experiment is conducted to measure the temperature of the contact surface under the operational conditions. The numerical results by the proposed method are in good agreement with the experiment results and the mean relative error is 2.96%. The proposed method can predict the temperature field on the rub-impact surface of the rotor-stator system accurately.
