| To better understand the mechanism of rub-impact failure and rub-impact between high-speed rotary transitions, the complete rotor-disc-casing rub-impact finite element model considering the flexible characteristic of the casing was established through the impact dynamic analysis method. And the transient process, local detail characteristics and vibration response of blade-casing rub-impact were studied. The simulation analysis results were compared with those of the physics test. It was found that the matching degree was good. And it proved that the simulation analysis model and simulation analysis method could describe the dynamic behavior of the rub-impact between the rotating blade and casing. And the effectiveness of the physics test was also proved. On this basis, different parameters influencing the rub-impact response were further analyzed. It was found that the gap between rotor and stator, relative velocity and stiffness ratio had great influence on rub-impact response. Some principles and laws explaining and predicting the phenomenon of rub-impact trouble were obtained. The research method and research results have some reference value for the diagnosis and prediction of the mechanical rub-impact trouble. |
