Abstract：

Taking a kind of cam with non-circular special-shaped section of cam hole(Isometric-trilateral sectional profiles), the components of assembled camshaft were modeled and assembled by Pro/Engineer, and the hydraulic connection process of assembled camshaft was simulated by ABAQUS. And the contact state of cam and shaft in the connection process was analyzed, in which the residual contact pressure, the residual contact area and the elastic recovery were used to characterize their contact state, and the target curves were fitted by statistical method. Finally, the relationship between the above three variables were established. The results indicate that with the increasing of hydraulic pressure and axial feeding amount, the residual contact pressure and the residual contact area show a near linear growth trend, while the elastic recovery shows a near linear decline trend. And the residual contact area has a positive correlation with the residual contact pressure and a negative correlation with the elastic recovery.
