摘　　要：超导托卡马克核聚变实验装置EAST的真空室窗口烘烤系统要求窗口温度达到150℃。为选取加热丝型号及确定其合理布局,采用ANSYS有限元分析软件进行热应力分析。分析结果显示,窗口大部分区域的温度分布及热应力分布较为均匀,并满足要求,按照ASME压力容器评定标准,均在安全系数内。同时,对温度梯度较大的区域提出可行性的附加方案,以降低可能出现的应力集中。The baking system of Experimental Advanced Super-Conducting Tokamk （EAST） vacuum vessel is necessary to obtain the baking temperature of 150 ℃. In order to define suitable alloy heaters and achieve their reasonable layouts, thermal analysis was carried out with ANSYS code. The analysis results indicate that the temperature distribution and thermal stress of most parts of EAST vacuum vessel ports are uniform, satisfied for the requirement, and are safe based on ASME criterion. Feasible idea on reducing the stress focus is also considered.
