1.前言蒸压釜是硅酸盐建材厂的关键设备.当按国外类似产品进行设计时,由于缺少强度计算文件而不能投产.我们受委托对现有引进结构进行强度计算和应力测试.这类蒸压釜是薄壳-实体组合式的压力容器(图1),结构的应力分析方法国内外尚未公开发表.由于结构形状复杂,经典的薄壳理论 1. Introduction The autoclave is the key equipment of the Silicate Building Materials Factory. When it was designed according to similar products from abroad, it could not be put into production due to lack of strength calculation documents. We were commissioned to perform strength calculation and stress testing on the existing imported structures. The autoclave is a thin shell-solid modular pressure vessel (Fig. 1). Structural stress analysis methods have not yet been published at home and abroad. Due to the complex shape of the structure, the classical thin shell theory
