摘要: 运载火箭是一个国家进入空间的主要手段，其制造水平对控制空间的进程至关重要。箭体结构作为运载火箭的主体部分，是火箭制造中的关键。经过几十年的发展，箭体制造技术逐渐从以手工操作为主的模式转向绿色化、自动化技术为主的模式。根据国内外运载火箭箭体结构制造情况，对箭体结构制造流程中的关键技术及其装备进行了详细的介绍，包括板材成型、铣削加工、钻铆、焊接和箭体对接这5个主要流程，总结了相关技术的国内外差距以及应用难点，为我国运载火箭箭体结构制造水平的发展提供参考。Abstract: Launch vehicles are the main means for a country to enter space, and its manufacturing level is crucial to the process of controlling space. As the main part of the launch vehicle, the structure of the rocket body is the key to rocket manufacturing. After decades of development, the rocket body manufacturing technology has gradually shifted from a manual operation-based model to a green and automated technology-based model. According to the manufacturing situation of the rocket body structure at home and abroad, this article gives a detailed introduction to the key technologies and equipment in the rocket body structure manufacturing process, including sheet metal forming, milling processing, drilling and riveting, welding and rocket body docking. The main process summarizes the domestic and foreign gaps and application difficulties of related technologies, and provides a reference for the development of my country's launch vehicle rocket body structure manufacturing level.
