多轴微动疲劳损伤行为
Multi-axial Fretting Fatigue Behavior
摘要
Abstract
The model of cylinder shape surface contact was applied to the investigation of fretting fatigue failure characters of 35CrMoA under multi-axial cyclic loading. And the fretting wear scar and fracture morphology were examined by optical microscope and scanning electronic microscope. The effect of fretting wear on material fatigue failure was discussed, too. Results of this study indicate that the oxide debris produced in the wear scar play important roles to surface material damage; fretting wear can accelerate the initiation of fretting fatigue crack and lead to material failure at the boundary of fretting and non-fretting area.关键词
