| 为了降低硫化罐齿啮噬式快开结构的应力，通常应对的方法是设计时增加法兰的厚度，因此结构较笨重，产品竞
争力不强。为此文中提出采用ANSYS对DN800硫化罐整体相连卡箍齿啮式快开结构进行有限元分析，得到各部位的应
力分布；在满足强度和抗疲劳性能的前提下，分别采用安全裕度法、JB 4732应力评定法对状态变量进行提取，以体积最
小为优化目标，对结构进行优化设计，优化后体积分别减少了12. 8%和14. 1%。比较发现采用安全裕度法对状态变量
进行提取，计算效率高，便于工程推广。 |

| In view of increasing the flange thickness to reduce the stress usually in the design of teech-locked quick open-
closure structure of vulcanizing tank . the structure is more bulky and the product is poor competitiveness. Taking the
teech-locked quick open-closure structure of DN800 vulcanizing tank as the research object, and through the finite
element analysis of ANSYS. the stress distribution in each part was obtained. In the precondition of satisfying the
strength and fatigue perfermance. the safety margin method and JB 4732 stress evaluation method were used to extract
the state variables. With the minimum volume as the goal to optimize the structure. the volume was reduced of 12. 8%
and 14. 1% respectively after the optimization. By comparison, it has a high computational efficiency and convenient for
engineering promotion by using safety margin method to extract the state variables. |
