摘　　要：超临界流体萃取釜作为一种典型的萃取装备,在石油化工中应用非常广泛,但是由于工作过程中快开及循环急剧引起的疲劳应力极易导致萃取釜变形乃至失效。为此,本文依据JB 4732—1995(2005年确认),利用有限元法对1500L大型超临界萃取釜装置进行了应力强度评定及疲劳强度分析,验证了所用结构合理性及可靠性。Supercritical fluid extraction vessel is one kind of typical extraction equipment widely used in the petrochemical industry, which the fatigue stress resulted from quick opening and dramatic cycling may cause deformation and failure. To avoide this, the stress analysis and fatigue strength assessment are processed on a large 1500L supercritical extraction kettle structural, based on JB 4732--1995 （2005 Version） standards. The sound results verified its rationality and reliability.
