Abstract
In order to realize the lightweight design of extraction kettle,based on finite element analysis of the 60 L supercritical CO2 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.关键词
