微动疲劳裂纹萌生位置及形成方式研究 - Many failures between tenon and mortise in aero - engine are founded under fretting circumstance , sometimes it is a main cause of failure and it is important to research the fretting fatigue life of tenon / morties
航空发动机中，有很多故障是由于榫联接构件在微动环境下失效引起的，进而造成了叶片和盘的损伤和破坏，因此研究榫联接结构的微动疲劳有重要的工程应用价值。 - 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
本文介绍了微动损伤的机理和微动疲劳寿命的研究方法；利用ug软件对燕尾榫联接结构创建了参数化实体模型；基于ansys软件平台求解弹性接触问题，获得了榫联接结构接触应力及接触状态量的分布；在已有微动疲劳寿命预测模型的基础上，引入载荷频率影响因子，对低周、高低周复合载荷作用下的燕尾榫联接结构进行了微动疲劳寿命的预测，与试验结果对比表明采用本文提出的方法预测榫联接结构的微动疲劳寿命是有效的。
