摘要
Abstract
Although countersunk bolt connection can ensure a good structure of aerodynamic shape and is often used in aircraft skin and other structures,a large error in the depth of countersink socket in the preparation process of countersunk holes is likely to occur due to limited equipment conditions,which brings hidden dangers to the composite laminated structure.To solve the problem,by combineing finite element simulation analysis,conducts a static tensile test of single nail and single shear,and studies the influence of countersink depth error on CERP connection performance.The results show that the shallower countersink socket has less effect on the static strength compared with the standard fossa depth value in the flush state,and the deeper countersink will lead to the decrease of the static strength of the structure,and the deeper the countersink socket is,the faster the static strength decreases.关键词
