| Abstract: | Aiming at the problems of severe vibration and noise during the operation of the twin screw compressor, a rigid-flexible coupling model of the screw rotor was established based on the modal superposition method, and the dynamic analysis of the screw rotor was performed through the flexibility theory and the collision theory. The change law of rotor deformation, stress, meshing force and rotor centroid were obtained, which has certain reference value for rotor structure design optimization. |
