Abstract EN
Fretting damage phenomenon often appears in the interference fit assembly.
The finite element model of hollow shaft and shaft sleeve was established, and the equivalent stress and contact stress were computed after interference assembly.
The assembly body of hollow shaft and shaft sleeve was in whirling bending load, and the contact status (sticking, sliding, and opening) and the distribution of stress along one typical contact line were computed under different loads, interferences, hollow degrees, friction coefficient, and wear quantity.
Judgment formula of contact state was fixed by introducing the corrected coefficient k.
The computation results showed that the “edge effect” appears in the contact surface after interference fit.
The size of slip zone is unchanged along with the increase of bending load.
The greater the interference value, the bigger the wear range.
The hollow degree does not influence the size of stick zone but controls the position of the junction point of slip-open.
Tangential contact stress increases with the friction coefficient, which has a little effect on normal contact stress.
The relationship between open size and wear capacity is approximately linear.
