摘　　要：本文采用有限元分析方法,以厚壁除砂器结构为研究对象,结合ASMEV-2规范中防止塑性填塌的非弹性分析方法进行结构静力分析,研究除砂器在压力、风载荷和地震载荷条件下防止塑性填塌失效的分析及评价。详细介绍和比较了弹塑性分析和极限载荷法2种非弹性分析方法,并结合实际工程案例重点介绍2种方法的材料本构关系、分析过程中载荷工况的详细计算步骤和结果评价。本文旨在为采用非弹性分析方法对结构进行防止塑性填璃分析计算提供参考。In this paper,the thick-wall desander structure in pressure,wind load and seismic load conditionswas carried out static structural analysis to study the inelastic analysis methods based on the finite element analysisand protection against plastic collapse in ASME VIII-2. The elastic-plastic stress analysis method and limit-loadanalysis method are introduced and compared in detail.Combined with actual engineeringcase,constitutiverelationofmaterial detailed calculation procedure and result evaluation were introduced.The aim of this analysis is to provide ananalytical reference for inelastic analysis method ofprotection against plastic collapse.
