摘　　要：利用ANSYS软件建立了EAST中性束注入器样机主真空室的有限元模型,分析了主真空室的受力情况;主真空室由三段组装而成,依据实际的材料和受力情况,分别对三段放置于地面以及整体连接放置在导轨上两种工作状况下进行结构静力学分析,得到了相应工作状况下的结构应力分布和变形情况。分析表明主真空室在两种工作状况下最大Von-Mises等效应力值小于材料屈服强度,主真空室结构是安全和稳定的,分析结果给主真空室下一步的优化设计和结构选材提供了依据。A finite element model for main vacuum chamber of EAST Neutral Beam Injector prototype was built with ANSYS software.The stress of the vacuum chamber was analyzed.The vacuum chamber was assembled by three sections,which should be analyzed respectively for structural statics with sections lying on ground and being laid on rails after connecting to obtain structural stress distribution and deformation under corresponding operating conditions.Analysis showed that the maximum Von-Mises equivalent stress of the vacuum chamber is less than material yield strength in two operating conditions.The structure of vacuum chamber is safe and stable.The calculation result provides the reference for the optimization and the selection of material.
