摘　　要：以某型机复合材料机身与主减后接头局部连接结构为研究对象,针对结构承面外载荷较大的特殊受载形式进行复合材料-金属接头机械连接技术研究。通过有限元仿真分析,确定了复合材料-金属接头的连接形式,并对复合材料机身结构连接区的局部铺层进行了优化,随后开展复合材料-金属接头连接结构的力学试验。结果表明,在给定载荷下,复合材料-金属接头机械连接结构具有足够的强度和刚度,满足设计要求。The mechanically fastened joint of composite structure that resists with special force can in- duce a high load out of plane. A typical composite structure is selected from a certain type of helicopter fuselage. An appropriate joint style is established by finite element analysis, the local lay-up of carbon fiber reinforced plastic（CFRP） fuselage is optimized, and then mechanical tests are carried out for the composite-metal joint structure. Theresults show that analysis data agrees well with test results, and / the mechanically fastened joint of composite structure has enough strength and satisfies design requests at given loads.
