Title The Design of mechanical device for Booster Assembly
Abstract
The rocket can not only be used in military weapon for national defense, but also become an important tool to develop space resources, science, technology in the national economy. A type of rocket is China's first rocket bundled with solid boosters, using high performance liquid core binding solid booster, effectively improve the rocket mission adaptability and flexibility. The purpose of this project is to study and design driving device used in solid rocket booster and core assembly. The design and study of this subject has greatly improved the reliability and efficiency of bundled rocket assembly, greatly shorten the assembly time of bound rocket, and has certain practical significance for the development of bundled rocket technology research.
This paper takes the design of booster assembly driving mechanical device as the key content, including:the design of mechanical structure, swinging hydraulic cylinder, screw drive mechanism. The design of mechanical structure includes the design of arm and support platform, among which the mechanical arm has functions of pushing and pulling, support platform with fixed mechanical arm achieve the radial and tangential movement of solid rocket booster. According to these requirements, in the design of driving device, various aspects of it need to be analyzed, such as structure, motion, force analysis.

1 绪论
从1957年苏联发射人类历史上的第一颗卫星以来，人类探索和开发空间资源的脚步变得愈发坚定和迅速。但是随着发射载荷种类和数量的增加，对于运载火箭运送不同用途和不同轨道的载荷也提出了更高的要求。对于运载火箭而言，在具备低廉发射成本的基础上同时具有灵活的任务适应能力将成为其核心竞争力。目前运载火箭主要有固体捆绑助推器和液体捆绑助推器两种捆绑方式，通过捆绑助推器可以直接提高运载火箭的推力，同时间接地达到增强运载能力和任务适应性的目的。两种助推器捆绑方式中，固体助推器相比之下起飞推力更大、可靠性更高、结构更简单且成本更低[1]，因此成为运载火箭捆绑助推器的首选方式。
