摘　　要：采用自主设计的微动疲劳加载设备对机械部件使用的TA16、DD6及FGH95三种合金材料的疲劳性能进行了研究。实验结果表明,这三种合金材料的初始疲劳裂纹首先出现在材料和微动垫相互接触的区域,这说明这种微动疲劳加载设备具有良好的性能。DD6和FGH95合金材料的微动疲劳寿命比TA16材料的要高。The anti fatigue performance of TA16, DD6 and FGH95 were studied by micro fatigue loading equipment.Experimental results show the three initial fatigue cracks of the alloy materials firstly appeared in the contact area between materials and micro pad. This illustrates that this independent design of micro fatigue loading equipment has a very good performance. The fatigue life of DD6 and FGH95 is longer than TA16.
