摘　　要：为了能确定某型民机复合材料平尾关键结构的中央连接结构的构型,通过建立中央盒段和中央对接构型的有限元模型,采用迭代设计的方法并严格满足相应的设计要求,保证两种构型的设计是最优的设计,在此基础上,以重量为首要目标进行了权衡分析。从权衡分析的结果来看,考虑到紧固件的增重,中央盒段构型在重量上的优势相对于中央对接构型是很小的,约为1%左右;而考虑到零件数量、装配的工作量,尤其是技术成熟度的指标,可以看到中央对接构型具备了相当的优势。In order to determine the central connection configuration of the key structure of civil aircraft composite horizontal tail, the finite element models of center-box and center-joint configurations were established. To ensure that the design of the two configurations is optimal, the iterative design method was used,and the design of two configurations strictty met the corresponding design requirements. On this basis,a trade study was carried out with the weight as the primary objective. The results of the trade study show that, considering the weight gain of the fasteners, the advantages of the center-box configuration in terms of weight relative to the center-joint configuration are minor,about 1 %. Considering the part number, assembly workload, especially the index of technology maturity,it can be seen that the center-joint configuration is remarkably superior.
