振动时效在铝合金薄壁件加工过程中的应用

Application of the VSR in Machining Process of Aluminum Alloy Thin-Walled Parts

介绍了振动时效法消除残余应力的机理,通过进行振动前后残余应力测试,验证了振动时效在铝合金薄壁件加工中的有效性,通过进行振动时效在薄壁件加工过程中的工艺,运用试验,得出振动时效在薄壁件加工中的应用方案。

The mechanism of vibration stress relief（VSR） is introduced,and the residual stress in thin-walled parts before and after VSR is measuered, which validated the effectiveness of VSR in machining process of aluminum alloy thin- walled parts. The relieving stress scheme of VSR used in thin-walled parts machining was drawn with processing experi- ment that VSR is used in the processing of thin-walled parts.
