摘　　要：贝类捕集器是核辅助厂房的重要设备,运行过程中同时承受内压和外部载荷。运用ANSYS程序中的板壳单元建立贝类捕集器的分析模型,对贝类捕集器的有限元计算模型进行自重、压力和接管载荷条件下的静力分析,用子空间迭代法(SUBSP)进行模态分析,以及进行地震载荷作用下的相应分析。计算结果按RCC-M规范的要求对贝类捕集器在各级准则条件下进行载荷组合与评定。The mussel trap is an important component used in nuclear power plant（NPP）. The loads requirements in design conditions contain both internal loads and external loads. The loads have dead weight, pressure, nozzles loads and seismic loads. The finite element model of the mussel trap is built with shell element using the structural analysis software-ANSYS. The stress analysis is based on linear elastic static analysis. The subspace iteration method is used for the modal analysis of the mussel trap. The static analysis is used for the mussel trap under deadweight, pressure and nozzle loads. Evaluation of all loads combinations stresses against the respective stress limit for plate-and shell- type components and linear type systems is done according to the requirements of relative criteria specified in RCC-M.
