摘要
ITER水平诊断窗口插件是用于安装可观察和测量等离子体相关参数的诊断设备和仪器的核心部件。窗口插件体积(2×2×3 m)和重量(大于43 t)均较大且处于悬臂安装状态,在装置运行期间窗口插件将受到较大的电磁力和电磁力矩,结构的强度将受到影响,同时作用在窗口上的载荷将对窗口插件内部集成的光学系统稳定性产生影响,容易造成光路不同。因此窗口插件结构的分析和优化非常重要。本文根据ITER组提供的概念化模型建立有限元模型,分析其在受到最大电磁力、电磁力矩及自重情况下对结构的影响。分析结果表明诊断窗口插件屏蔽板(BSM)连接处及提升法兰处均有较大的应力集中,通过改进结构设计进行优化分析后,窗口插件在结构上均能满足强度和变形要求。
The equatorial port plug（EPP） is a key part used for the installation of the diagnostic system/instruments to observe and measure the parameters relevant to plasma.With its big volume（2×2×3m） and heavy weight（over 43t） especially its cantilever-shape in installation,EPP is subjected to great electromagnetic force/torque thus affecting its structural strength.Moreover,the loads acting on EPP will affect the stability of optical system inside EPP so as to be easy to cause different optical paths.The structural analysis/optimization is therefore very important to EPP.According to the conceptual model provided by ITER（international thermonuclear experimental reactor）,an FEA model based on the software ANSYS is developed to analyze how the maximum electromagnetic force/torque and gravity of EEP itself affect its structure.The results revealed that the stress is highly concentrated in both the positions where the BSM（blanket shielding module） is joined and the lifting flange is provided.The improved structural design and optimization analysis verified that the EPP structure is available to meet the requirements for both strength and deformation.
