Finite Element Analysis of Interference Joint of Rotor and Crankshaft Based on ANSYS

Yi Liao

Abstract

In the study of new rotary compressor which is used for Air Conditioning,in order to judge whether the magnitude of interference of specified serial compressor meets the requirement,the finite element and mechanical model of the interference joint between roter and crankshaft is established by used contact-finite-element methods.The paper carries out the finite element analysis on ANSYS and attains the stress distribution in interference joint.It is concluded that the bonded surface do not move at minimum interference and the material do not fail at maximum interference meets the product design requirement.
