摘　　要：根据Ⅲ型活性炭碘吸附器研制要求,从力学分析角度,用有限元法建立吸附器分析计算模型,进行自重、设计压力和运行压力的静力分析、模态分析和地震载荷下的应力分析与评定,论证了Ⅲ型活性炭碘吸附器在不同工况下的结构完整性,阐述了静力和地震载荷下结构设计中应改进和加强的薄弱环节。An active carbon absorber is mainly used for radioactive iodine absorption and gas purification in an nuclear power plant. According to technical requirement of the Type Ⅲ absorber developed at Shanghai Nuclear Engineering Research and Design Institute, finite element analysis （FEA） was used for its mechanics analysis. Static analysis under dead weight, design pressure and operating pressure, modal analysis, and seismic analysis were performed. The structure integrity of Type III active carbon iodine absorber was satisfied under different service conditions. The structure weakness was clarified under static and seismic loads, and the structure design was improved based on the FEA results.
