干涉量对复合材料层合板疲劳寿命的影响

摘要

The fatigue life of composite materials which used interference-fit joint is different from the ones which used slip-fit The comparative study of this difference conclud: the fatigue life of composite materials which used interference-fit joint is higher than those used slip-fit And also verify that the effect of different interference fit level on the fatigue life of composite materials Finally this thesis proves that the best interference quantity is 082％～0.98％.%试验研究了干涉配合连接和间隙配合连接的复合材料板疲劳寿命的差异.验证了采用干涉配合连接的复合材料板的疲劳寿命远高于采用间隙配合连接的复合材料板的疲劳寿命,得出了不同的干涉量对复合材料板疲劳寿命的影响等,并得出其最佳干涉量为0.82%～0.98%.
