| 中文摘要: |
| 针对国内对倒锥密封端盖研究不足、缺乏设计理论指导、参数设置不够合理等问题，借助于ANSYS软件对某公
司生产的倒锥密封端盖进行应力强度分析；选取轴向变形UY为目标函数，以最大应力Smax为状态变量，以Rh／Ra、lc／Ra、
Z／Ra作为设计变量，建立了优化设计数学模型；并在此基础上，运用ANSYS优化设计功能对其进行了优化分析。结果
表明：当fcl/Ra-0. 13、Rb,/Ra-0. 68、Zc/Ra≈0.28时结构较为合理。通过优化前后对比，最大应力.Smax减小了46. 9%，最
大轴向变形UY减小了50. 6%，优化效果明显。 |

| Aimed at the problem of inadequate study, lacking design theory guidance, unreasonable parameter settings to
the inverted cone sealing cover in China. the stress intensity of sealing cover was analyzed by ANSYS; the axial
deformation Uy was selected as objective function. the maximum stress Smax as state variables, Rh/Ra, Lcl/Ra and lc/Ra
as design variables. and the optimization design mathematical model was established; then it was optimized by
optimization function of ANSYS. Analysis shows that while Ld/Ra≈0. 13 , Rb/Ra≈0. 68 , Lc/Ra≈0. 28 , the structure is
reasonable. Through the optimization. the maximum stress Smax decreased by 46. 9% ，the maximum axial deformation
UY decreased by 50. 6% . which shows the optimization effect is obvious. |
