摘　　要：在有限元方法的基础上,利用变密度法对单搭接胶接接头搭接区域的被粘物形状进行了拓扑优化,通过曲线拟合得到了较为合理的轮廓。拓扑优化的结果表明:在体积减少20%的情况下,胶接结构的强度不会降低;经拓扑优化后,胶层中剪切应力的峰值比优化以前增加不大,约1%。Based on finite element method, variable density method was employed to optimize the configuration of adherends in overlap region, and the curve fitting was applied to attain proper configuration. It showed that the strength of adhesive bonded structure would not decrease with a volume decrease of 20 %. It also showed that the peak value of the shear stress in the topologically optimized model was about 1% larger than that in original model.
