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。 According to the research and development requirements of type Ⅲ activated carbon iodine adsorber, from the perspective of mechanical analysis, the model of adsorber analysis and calculation was established by finite element method, and the static analysis, modal analysis and stress analysis under the earthquake load of self-weight, design pressure and operating pressure The structural integrity of Type III activated carbon iodine adsorbers under different operating conditions was evaluated and evaluated. The weak links that should be improved and strengthened in structural design under static and seismic loads were described.
