摘　　要：利用ANSYS-APDL工具,研究了不同形状的毛边对复合材料胶结接头应力分布和应力峰值的影响,确定三角形毛边为优选毛边方案。对三角形毛边胶结接头进行了一系列优化设计,优化结果表明,随着隔板厚度的增大,胶层厚度逐渐增厚,而夹角减小;同时还发现,当胶层厚度取0.3mm,夹角取30°时,无论接头结构尺寸如何变化,应力峰值始终处于较低的水平。这说明将胶结接头控制在这样的尺寸下,即使不是最优尺寸,也能获得很好的工艺效果。By using ANSYS-APDL, the effect of various spew geometry on stress distribution and maximum value in adhesive joints are investigated, and the triangular spew is selected. A series of optimization designs are executed to triangular spew, the results show that adhesive thickness gradually increase and angle decrease with the increase of partition thickness. Synchronously, when adhesive thickness is 0.3mm and angle is 30°, maximum stress values are lower whatever spew dimensions. This implies that if the joint is controlled in this size, the technical effect will be nice even through it is not the optimization design.
