摘　　要：燃烧室是固体火箭发动机中的一个重要结构。燃烧室内表面有一层绝热层,用于确保燃烧室工作时壳体不会因高温而被破坏。初始作业时绝热层表面较为光滑,需要被打磨毛糙,以便进行下一工序。设计了一种体型较小、运行灵活的轮式打磨机器人,可在燃烧室内部运行并自动打磨。绝热层表面有一定高度、宽度的凸起,因此打磨机器人设计有独立悬挂,用来减小跨越凸起时发生的振动或冲击。建立了打磨机器人动力学模型,并利用ADAMS软件对相关设计参数进行分析,以为后续设计提供理论依据。The combustion chamber is an important part in solid rocket motor.There is an insulation layer on the inner surface of the combustion chamber to protect the shell from being damaged by high temperature.The surface of the initial insulation layer is smooth,which needs to be polished rough for the next step.A small and flexible wheeled grinding robot was proposed,which can run inside the combustion chamber and grind automatically.The surface of the insulation layer has some bulges of a certain height and width,so the grinding robot was designed with independent suspension to reduce the vibration or shock when crossing those bulges.The dynamic model of grinding robot was established,and the related design parameters were analyzed by using ADAMS software,which provided a theoretical basis for the subsequent design.
