Abstract
Assembly of shaft and hub by an interference fit is a classical connection with known advantages and disadvantages.The advantage being the level of possible torque transfer while the disadvantage is a possible fretting fatiguefailure at the points of stress concentration. The pressure distribution in the contact is the source responsible for the fatigue failure. The distribution can be improved by design modification done directly on the contacting surfaceswhich however requires a very high production precision. Alternatively it is shown, how shape optimization of thehub side can improve the pressure distribution significantly.
