摘　　要：将复合材料层合板补片胶结修理的方法应用到飞机受损结构的维修中,将补片固定在损伤结构上从而恢复结构强度和传力路径。基于ANSYS Workbench有限元分析软件,针对飞机复合材料层合板胶结修补的结构特点和使用状态进行了分析,从而得出最优的复合材料补片的结构参数,包括补片的直径和厚度。结果表明,使用复合材料层合板胶结修理能够有效提高铝合金板结构的强度,一定程度上恢复受损结构的刚度。进一步优化设计补片最佳结构,提高了胶结修理的可操作性和经济效益。The composite plywood patch-bonded method is used for repairing the damaged structure of the aircraft.The composite plywood patch is bonded to the damaged structure,and then the strength and force transmission path can be restored.Based on the ANSYS Workbench finite element analysis software,the structural characteristics and usage status of the composite plywood patch-bonded repairing model is analyzed,and then the optimal structural parameters of the composite patch are obtained,including the diameter and thickness.The results show that the composite plywood patch-bonded method could effectively restore the rigidity of the structure,improving the strength and load capacity of the structure.Furthermore,the engineering operability and economic benefits can also be improved by optimizing the patch structure.
