摘　　要：大曲率碳纤维蒙皮固化成型后会产生较大的固化变形,导致蒙皮与骨架之间产生间隙,在铆接装配时,蒙皮将承受一定的装配载荷。为控制大曲率碳纤维蒙皮铆接装配过程中的装配载荷,构建了复合材料蒙皮铆接过程数值计算模型,并以铆接过程中蒙皮最大应变最小,以加载点、约束点支反力小于临界值为约束条件,建立了铆接顺序优化模型,通过遗传算法及ABAQUS二次开发实现优化模型求解。结果表明,优选的铆接顺序下复合材料蒙皮最大应变明显小于按工艺经验顺序铆接时的应变,证明了该方法的有效性和可行性。After curing and molding,the large curvature carbon fiber skin will produce a large curing deformation,resulting in a gap between the skin and the skeleton,and the composite skin will bear a certain assembly load when riveting assembly.In order to control the assembly load in the assembly process of large curvature carbon fiber skin riveting assembly,a numerical calculation model of the riveting process of composite skin was constructed,and a riveting sequence optimization model was established with the maximum strain of the skin during the riveting process being the smallest,and the loading point and constraint point support reaction force being less than the critical value as the constraint conditions,and the optimization model was solved by genetic algorithm and ABAQUS secondary development.The results show that the maximum strain of the composite skin under the preferred riveting order is significantly smaller than the strain during riveting according to the process experience order,which proves that the method is effective and feasible.
