Finite element analysis (FEA) was made for a clamp structure with large diameter, and the data associated with stiffness was extracted. The result shows that the stiffness must be considered while designing a clamp structure with large diameter. Basing on this design and making use of FEA software to obtain rigidity-concerned burst data, the parameter value influence on clamp structure was discussed to provide the reference for later design.%在大直径卡箍结构设计实例的基础上,利用有限元分析软件获取与刚度相关的成组数据,讨论了各参数的变化对卡箍结构刚度的影响,为今后类似结构的设计提供依据.
