摘要

托卡馬克裝置是目前最重要的聚變?cè)O(shè)備之一，而大型聚變實(shí)驗(yàn)裝置CFETR便是一種世界上最具競(jìng)爭(zhēng)力的第二代托卡馬克裝置，它的運(yùn)行狀態(tài)與壽命對(duì)于聚變技術(shù)的發(fā)展有著十分重要的影響。由于CFETR長(zhǎng)時(shí)間的運(yùn)行，設(shè)備的執(zhí)行器會(huì)受到不同程度損傷，嚴(yán)重?fù)p傷的執(zhí)行器需要進(jìn)行更換或維護(hù)。然而，在高溫、強(qiáng)輻照和高真空等復(fù)雜環(huán)境下，如何對(duì)執(zhí)行器進(jìn)行維護(hù)成為了一大難題，而采用三自由度機(jī)器人進(jìn)行執(zhí)行器的維護(hù)則成為了較為有效的解決方案。因此，本文研究了基于三自由度機(jī)器人的CFETR維護(hù)執(zhí)行器問(wèn)題。

首先，本文闡述了CFETR的基本工作原理與執(zhí)行器的功能以及成分。之后，針對(duì)CFETR執(zhí)行器維護(hù)需求，提出了三自由度機(jī)器人的方案，并給出了整體結(jié)構(gòu)設(shè)計(jì)與運(yùn)動(dòng)學(xué)建模方案。在此基礎(chǔ)上，本文設(shè)計(jì)了機(jī)器人控制算法，實(shí)現(xiàn)了機(jī)器人的路徑規(guī)劃與控制。實(shí)驗(yàn)結(jié)果證實(shí)，該機(jī)器人成功地實(shí)現(xiàn)了對(duì)CFETR執(zhí)行器的維護(hù)。

在CFETR執(zhí)行器維護(hù)方面，本文的研究結(jié)果具有很好的可行性和實(shí)用性，提供了一種行之有效的CFETR執(zhí)行器維護(hù)方法，并為CFETR的長(zhǎng)壽命運(yùn)行提供了技術(shù)支持。
