摘要：
Aiming at the phenomenon of aircraft engine blade-casing rubbing, this paper established a blade-casing Hertz-rubbing model considering the rotation effect and friction thermal effect. The influence factors of rubbing radial deformation were analyzed. The accuracy of the model was verified by comparing with the experiment results of existing normal rubbing force model. Moreover, the influence of rotation speed, stiffness coefficient, friction coefficient on the rubbing radial deformation were also analyzed. The results of the thermo-solid coupling simulation analysis on blade showed that the friction thermal effect had a certain influence on the overall radial deformation. © 2019, Shanghai Jiao Tong University Press.
