| Abstract: | Threaded fastener is the important type among all the fasteners.Fastenings with bolts are widely used because of its simple construction and convenient installing.For the bolts which should support variable loads and impingement loads,flexible ones are often used on aeroengines.In this paper,a kind of flexible bolts with high fatigue strength which can improve the supporting conditions of bolts is introduced.What is more,some measures to improve the fatigue strength of elastic bolts are presented in some respects of reasonable material choice,structure improvement,and surface strengthening,etc. |
