摘要: 采用有限元分析软件对铀基混合堆次临界能源包层及其支撑固定结构的相关零部件开展了瞬态冲击分析，得到了各零部件相关结构的最大应力值、应力分布云图和变形分布云图；并按相应的评价准则进行结构的强度和刚度校核，计算结果表明次临界能源包层各零部件能够满足计算工况下的强度和刚度要求。Abstract: Based on the transient dynamic analysis of the subcritical energy blanket and the support fixed strcture, this paper gives the stress distribution contours and deformation contours of all parts. The analysis results show the maximum stress value of the subcritical energy blanket of various parts is below the allowance stress and satisfy the strength requirement. The deformation for various parts is reasonable, and no significant displacement and instability phenomena occurs .
