干涉对复合材料叠层板螺栓连接疲劳强度的影响

Abstract

Abstract: An experimental study on fatigue life of interference-fit composite joint is presented. The experimental results obtained show that suitable interference can certainly increase fatigue life in comparsion with the push-fit case.For the material and laying studied in this paper, when the interference is 2%, the fatigue life is increased two to three times. An explaination for the result is given. In order to obtain the currect result, some methods of processing and assembling are emphasized in the experiment. An explaination is given for the definition1 of fatigue life limitation and the choice of the best interference.

Key words: push-fit joint, interference-fit joint, fatigue life
