509 高張力鋼のフレッティング疲労に及ぼすブリッジ型パッドのスパン長さの影響(OS フレッティング摩耗と疲労)

概要

論文の詳細を見る
Effect of contact pressure on fretting fatigue life under a given stress amplitude in a high strength steel was studied using bridge-type pads with various span lengths. With an increase in contact pressure, the fretting fatigue life showed a minimum and a maximum when the span length of pad was small. When the span length of pad was large, the life showed only a minimum. These changes in life with contact pressure had no relation to those in tangential force between the pad and the specimen. When the life showed a minimum, the main cracks responsible for failure were initiated at the central portion of the fretted area. This suggested that local stress concentration occurred there.
