摘　　要：研究了一种新型光学相机碳纤维复合材料桁架结构的胶接装配方法。对胶接装配的工装设计、胶黏剂选择、表面处理、胶层控制、装配原则进行了详细的分析。通过制定科学的装配方法和工艺,减小了桁架结构的装配应力,提高了装配精度和稳定性,最后对装配后的桁架结构进行了正弦和随机振动试验。结果表明采用该胶接装配法装配的桁架具有较高的装配精度和稳定性,可为空间光学相机中复合材料桁架结构的装配提供一种崭新的思路和方法。The adhesive assembly method of a new type of optical camera carbon fiber composite truss structure was studied.The tooling design,adhesive selection,surface treatment,adhesive layer control and assembly principle of bonding assembly were analyzed in detail.By formulating scientific assembly methods and processes,the assembly stress of truss structure was reduced and its assembly accuracy and stability were improved.Finally,the sinusoidal and random vibration tests of the assembled truss structure were carried out.The results show that the truss assembled by this bonding assembly method has high assembly accuracy and stability.It provides a new idea and method for the assembly of composite truss structure in space optical camera.
