摘要: 对AlSn20Cu轴瓦进行了疲劳试验,观察到疲劳裂纹的萌生及扩展过程,并以计算所得轴心轨迹、油膜压力和合金层应力分布为依据,分析了轴瓦的疲劳过程,与试验结果相吻合,从而为轴瓦的疲劳裂纹分析提供了新的研究方法。

关键词: 裂纹, 压力, 油膜压力, 轴瓦

Abstract: Fatigue crack initiation and propagation in AISn20Cu bearing are observed by fatigue test. Journal center orbit, oil film pressure and stress distribution on alloy got from calculating are taken as the basis for analyzing the bearing fatigue process and result accords with the test result, which provides a new way for studying fatigue crack in bearing.

Key words: Bearing, Crack, Oil film pressure, Stress
