Abstract

The occurrence of rubbing failure in the rotor blade-casing system directly impacts the engine's safety. To investigate the rubbing behavior of the system, a numerical model of the rotor blade-cassette system, based on the fluid-thermal-solid coupling method, was established. Fluid-thermal-solid coupling analysis was conducted, and the distribution of blade temperature and stress was studied. The findings emphasize the necessity of considering fluid-thermal-solid coupling in the analysis of rubbing phenomena. The rubbing behavior of the rotor blade-casing system exhibits regional characteristics. Within the rubbing influence range, the temperature increases with contact time. Simultaneously, the stress uniformly decreases along the rubbing point, forming a ring-like pattern around it. The results provide some theoretical basis for revealing the rubbing mechanism of the rotor blade-casing system.
