本文详细描述了复合材料等刚度多钉螺接载荷分配的测试过程。着重探讨载荷传递的测试方法以及连接的迭层顺序对载荷分配的影响。4钉螺接试件系纤维增强碳/环氧复合材料制成,各螺栓串联排列并沿钉孔的中心连线方向施加拉伸载荷。本文通过对螺栓位移量的测量,得以确定连接中各钉承载的百分比,发现多钉连接的载荷分配对迭层板中±45°铺层含量相当敏感,±45°纤维含量的增加将加剧多钉螺接载荷分配的不均。受载最严重螺栓的承载百分比亦随迭层板中±45°纤维含量的增加而呈上升趋势。 This paper describes in detail the testing process of the load distribution of rigid nodules such as composite material. Focus on the load transfer test method and the connection of the stacking sequence of the load distribution. 4 Nail screw test pieces made of fiber-reinforced carbon / epoxy composite materials, the bolts arranged in series and along the nail hole in the direction of the center connecting line to exert tensile load. In this paper, the bolt displacement is measured to determine the percentage of each nail loaded in the connection. It is found that the load distribution of multi-nailed connections is quite sensitive to the ± 45 ° ply content in the laminate, and the increase of ± 45 ° fiber content will increase more Nail screw load distribution of uneven. The loading percentage of the severely loaded bolts also increased with an increase of ± 45 ° fiber content in the laminate.
