| 中文摘要: |
| 为了实现萃取釜的轻量化设计，采用ANSYS软件对60 L超临界CO2萃取釜进行有限元分析，得出萃取釜卡箍
式快开结构的应力分布；在满足强度和抗疲劳性能的前提下，分别采用安全裕度法和JB 4732应力评定法提取状态变
量，以体积最小为目标进行优化设计。结果表明：2种方法优化后的效果明显，优化后的体积分别减少了22. 5%和
24. 2%。优化设计达到了轻量化目的，同时为萃取釜卡箍式快开结构优化设计提供有益参考。 |

| ln order to realize the lightweight design of extraction kettle, based on finite element analysis of the 60 L
supercritical C02 extraction kettle, the stress distribution of the hoop-locked quick closure structure of supercritical
extraction kettle was obtained. Under the condition of meeting the requirements of strength and fatigue resistance, the
safety margin method and JB 4732 stress evaluation method were used to extract the state variables, with the minimum
volume as the object to optimize the structure. The results show that the effects of the two methods are obvious. and the
volume was reduced of 22. 5% and 24. 2% respectively after the optimization and the purpose of lightweight design is
achieved. And it provides references for the structural optimization design of quick closure device of extraction kettle. |
