Effects of Contact Load and Contact Curvature Radius of Cylinder Pad on Fretting Fatigue in High Strength Steel

Source

Fretting fatigue of high strength steel was studied at various contact loads using bridge-type fretting cylindrical pads with various contact curvature radii. The fretting fatigue life showed a minimum at a certain contact load irrespective of the pad radius even though the frictional force increased monotonously with contact load. At a high contact load, the fretting fatigue life remained almost unchanged with a change in pad radius. At a low contact load, however, the fretting fatigue life increased with an increase in pad radius even though the frictional force was independent of the radius.
