Abstract: The connection between the compressor housing and the stator is achieved through thermal interference fit, with the resulting clamping force and deformation directly influencing the reliability and performance of the compressor. Therefore, a comprehensive study of these factors is essential. This research employs ANSYS simulation software for analysis and validates the accuracy of the simulation model. It investigates the effects of interference fit amount and temperature variation on the housing-stator clamping force and associated deformations under various loading conditions. The results indicate that the interference fit amount exhibits a linear relationship with both the clamping force and the deformation. In contrast, temperature shows a linear relationship with clamping force but a nonlinear relationship with deformation. Thus, the influence of temperature should be considered in the design of compressor interference fits. Provides both theoretical and practical guidance for the design of interference fits between aluminum compressor housings and stators.
