Fretting Fatigue of a Kind of Flexible Pin of Double Cantilever Beam

The double cantilever beam flexible pin structure with interference fit is usually adopted by the planetary gear shaft of large gear gearbox, and the interference fit structure at this location is prone to fretting fatigue. The maximum and minimum values of effective interference are theoretically c...
