摘要

托卡马克装置是目前最重要的聚变设备之一，而大型聚变实验装置CFETR便是一种世界上最具竞争力的第二代托卡马克装置，它的运行状态与寿命对于聚变技术的发展有着十分重要的影响。由于CFETR长时间的运行，设备的执行器会受到不同程度损伤，严重损伤的执行器需要进行更换或维护。然而，在高温、强辐照和高真空等复杂环境下，如何对执行器进行维护成为了一大难题，而采用三自由度机器人进行执行器的维护则成为了较为有效的解决方案。因此，本文研究了基于三自由度机器人的CFETR维护执行器问题。

首先，本文阐述了CFETR的基本工作原理与执行器的功能以及成分。之后，针对CFETR执行器维护需求，提出了三自由度机器人的方案，并给出了整体结构设计与运动学建模方案。在此基础上，本文设计了机器人控制算法，实现了机器人的路径规划与控制。实验结果证实，该机器人成功地实现了对CFETR执行器的维护。

在CFETR执行器维护方面，本文的研究结果具有很好的可行性和实用性，提供了一种行之有效的CFETR执行器维护方法，并为CFETR的长寿命运行提供了技术支持。
