  1. First, the theory of fretting wear and studies on fretting fatigue were introduced and the parametric method was used in the process of creating the model of dovetail joints in ug software. the elastic contact problem is analyzed in finite element method ( fem ) and is used to the parameters " distribution and contact stress of the joint are obtained on the base of ansys code. with the effect factor of load frequency, the prediction method of fretting fatigue life of dovetail joint under low and high / low cycle complex load is proposed

    本文介紹了微動損傷的機理和微動疲勞壽命的研究方法；利用ug軟體對燕尾榫聯接結構創建了參數化實體模型；基於ansys軟體平臺求解彈性接觸問題，獲得了榫聯接結構接觸應力及接觸狀態量的分佈；在已有微動疲勞壽命預測模型的基礎上，引入載荷頻率影響因子，對低周、高低周復合載荷作用下的燕尾榫聯接結構進行了微動疲勞壽命的預測，與試驗結果對比表明採用本文提出的方法預測榫聯接結構的微動疲勞壽命是有效的。

  4. A series of tests were performed on the self - made fretting wear test rig to examine the fretting wear of steels, by taking the wear depth of steel wires as a characterization parameter describing the fretting wear in relation to contact load and fretting time. the results demonstrates that the fretting wear depth increases with the increasing of the contact load and fretting time

    結果表明，鋼絲試樣的微動磨損深度隨著接觸載荷和微動時間的增加而呈增長趨勢，但由於接觸面積和接觸應力在微動磨損過程中隨著接觸載荷和微動時間的變化而變化，使磨損深度在不同磨損工況下增長趨勢不同。
