FEM Analysis of Stress on Shaft-Sleeve Interference Fits

Abstract:

Interference fit is one of the principal difficulties during Remanufacturing. Research on shaft–sleeve interference fits stress characteristics and influencing factors are very important for the study on remanufacturing disassembly method. Different interference, shaft diameter, wall thickness and mating length are taken into account and various FEM contact analysis calculations were carried out by orthogonal test. The relationship between influencing factors and contact stress were also investigated with the stepwise multiple regression analysis, optimum regression equation was established and analyzed by response surface method. The analysis result shows that interference is the most significant factor that affecting the contact stress
