滚压加工技术提高高强航空紧固件的疲劳强度

Improvement of Fatigue Strength of High Strength Aerospace Fastener by Using Rolling

介绍了航空紧固件滚压加工技术,指出采用适当的设计和合理的加工工艺,可将高强紧固件疲劳强度和疲劳寿命提高数倍,但加工中必须加以控制,以防过度加工。

The rolling technology for aero space fastener is introduced. It is pointed out that the fatigue strength and fatigue life of high strength fastener can be increased by several times by using suitable design and reasonable technology, but the process must be controlled and overworking should be avoided.
