摘要
机身装配作为空间相机制造的一个关键环节,对保证机身的力学性能至关重要。为了提高空间相机机身的结构刚度和稳定性,针对机身的装配环节进行了研究。研究了胶接装配方法及其相对于传统机械连接法的优势,对胶接法的装配精度进行了分析。研究了胶接装配的各种粘接要素,并进行了分析和实验。最后对装配后的机身进行了力学和热学实验,释放了装配应力,验证了机身的力学性能。实验结果表明:胶接法的装配变形可以控制在0.01 mm以内。采用胶接方法并按照装配工艺进行装配,可以减少装配应力,提高机身的装配精度和稳定性,符合机身结构的装配要求。
As a key link of the space camera manufacture, assembly of space camera＇s body is very important to ensure that the mechanical properties of the structure. To improve the stiffness and stability of space camera frame structure, the assembly sections of space camera＇s body were studied in this paper. Compared with the traditional mechanical connection method, the advantages of bonding assembly method were studied, and assembly precision of bonding methods was analyzed. The various elements about the bonding assembly method were studied and tested. At last, the mechanical and thermal test of the frame structure were completed, the assembly stress was released, the mechanical properties of camera＇s body was verified. The experimental results show that the deformation of the bonding assembly can be controlled in less than 0.01 ram, the bonding assembly technology is helpful to reduce the assembly stress, improve the accuracy and stability of the camera＇s body, meet the requirements of the frame structure assembly of the space camera.
