摘要: 探讨了一种新型聚变-裂变混合堆次临界能源包层的有限元建模方法。应用ANSYS Workbench软件建立了该次临界能源包层的3D结构模型，并对该模型进行了稳态热分析、热-力耦合分析，获得了包层各零件的应力分布及变形分布，分析了包层各零件的强度、刚度，利用热-力耦合分析找到了该次临界能源包层的薄弱环节。计算结果表明，该包层满足强度、刚度要求，为该次临界能源包层的设计和改进提供了理论依据。Abstract: A new type of subcritical energy blanket for fusion fission hybrid reactor was introduced. A 3D finite element model (FEM) of the blanket was established with ANSYS Workbench. The steady-state thermal analysis and thermal-mechanical coupling analysis of the model were carried out. The stress and deformation distributions of all parts of the blanket were obtained. The strength and stiffness of all parts of the blanket were analyzed. The weak position of the blanket was found by the thermal-mechanical coupling analysis. The results show that the strength and stiffness of the blanket meet the requirements. It provides a theoretical basis for the design and improvement of the new subcritical energy blanket.
