摘要
本文对Ｔ３００／ＱＹ８９１１π／４层压板机械连接干涉配合进行了静拉伸挤压和拉－拉疲劳试验。与滑配合比较，干涉使静挤压强度略有提高，但能使疲劳寿命增加数倍。文中用有限元方法计算了两种配合的孔边应力分布。并对疲劳损伤用Ｘ射线作了检测，初步分析了干涉配合的增寿原因。
An experimental study on tensile-tensile fatigue life of interference-fit mechanical joint in composite laminates is presented. In comparison with the push-fit case,the results obtained show that the suitable interference can significantly increase fatigue life,but slightly raise static strength. The stress distribution in a hole edge region is calculated by means of finite element method and the damage area of the hole edge is detected by X-ray nondestructive for both two cases. The reason why the interference-fit joint increases fatigue life is also discussed in the paper.
