摘　　要：薄壁二极铁真空室由于其特殊的作用被应用在HIAF装置的部分位置,由于真空室的壁非常薄,在抽真空状态下易变形,因此对其进行有限元分析明确其在抽真空状态下的应力、变形情况很有必要。本文利用ANSYS Workbench对薄壁二极铁真空室进行结构静力分析,在静力分析的基础上对真空室进行多目标优化及结构优化得到了最佳设计点和可以减少的质量,为薄壁二极铁真空室的后续设计提供一定的参考。The mechanical properties of the thin-walled dipole-magnet vacuum chamber, made of pure iron and dedicated to the high intensity heavy-ion acceleration facility （HIAF）, were mathematically modeled and numerically simulated in finite element method with ANSYS Workbench for design optimization. The influence of the geometry and configuration of the strengthening ribs on the static stress and deformation profiles of the ultra-high vacuum （UHV） chamber was investigated. The simulated results show that the height of the strengthening rib strongly in- creases the strength and rigidity of the vacuum chamber, and that the optimized vacuum chamber meets the stringent mechanical requirements. In addition, the multi-objective optimization and structural optimization were performed, with software Design Exploration and Shape Optimization, to minimize the stress, deformation and mass of the vacuum chamber.
