摘　　要：对含有大面积减薄区的高压汽包进行了弹性有限元分析,借鉴分析设计规范JB 4732—95对高压汽包进行了应力评定。采用弹塑性有限元分析方法计算了含大面积减薄区高压汽包的极限载荷,结果表明汽包是安全的,并且具有较大的安全裕度。Finite element method is used to analysis the stress field of high pressure vapor bag with large scale thin walls and analysis design code (JB4732—95) is used to assess the stress of the vapor bag The limited load of the vapor bag is calculated by elastic plastic finite element analysis The results show that the vapor bag with large scale thin walls is safe and it has sufficient safety factor
