Abstract

A review on optimization of adhesively bonded spar-wingskin joint (SWJ) of laminated fiber reinforced polymer (FRP) composites subjected to pull-off load is presented in this article using three-dimensional finite element analysis. Von Mises stress components have been computed across the width of joint at different interfaces viz. load coupler-spar, and load coupler-wingskin interfaces. Further, the weight of SWJ structure is considered as the objective function which needs to be minimized for optimization. In the first step, the material and lamination scheme of the FRP composite materials used for SWJ are optimized, and, in the second step, the geometrical parameters have been optimized on the basis of minimum von Mises stress and weight. Further, the effects of the material, lamination scheme, and geometrical parameters on the von Mises stress and weight have been validated using the Analysis of Variance (ANOVA) approach as prescribed by the Taguchi method. The results show that the material and spar thickness are the most significant factors influencing von Mises stress. The weight analysis reveals that there is a significant effect of change in material and wingskin thickness on SWJ performance. Suitable design recommendations have been made for SWJ in terms of material, lamination scheme and geometrical parameters.

拉脱载荷作用下FRP复合材料粘接翼皮-翼皮接头的优化研究

本文采用三维有限元分析方法，对层合纤维增强聚合物（FRP）复合材料在拉脱载荷作用下的翼梁翼皮节点（SWJ）的优化设计进行了综述。Von Mises应力分量已在不同界面（即荷载耦合器翼梁和荷载耦合器翼板界面）的整个接头宽度上进行了计算。此外，SWJ结构的权重被认为是需要最小化以进行优化的目标函数。在第一步中，对用于SWJ的FRP复合材料的材料和层压方案进行了优化，在第二步中，基于最小von Mises应力和重量对几何参数进行了优化。此外，材料、层压方案和几何参数对von Mises应力和重量的影响已经使用田口方法规定的方差分析（ANOVA）方法进行了验证。结果表明，材料和翼梁厚度是影响von Mises应力的最重要因素。重量分析表明，材料和翼皮厚度的变化对SWJ性能有显著影响。从材料、层压方案和几何参数方面对SWJ提出了合适的设计建议。
