关键几何参数对药柱贮存刚度的影响分析

Analysis on influence of key geometric parameters on grain rigidity

基于粘弹性理论,利用ANSYS有限元软件,建立药柱结构的有限元模型,确定影响药柱贮存刚度的关键几何参数,对不同药柱结构贮存期内的药柱刚度进行分析,研究不同几何参数对药柱贮存刚度的影响敏感度,为药柱结构完整性设计提供理论分析与研究基础。

Based on the viscoelastic theory and by using finite element software ANSYS, the finite element model of grain structure was established to determine the key geometric parameters influen cing the grain storage stiffness. The grain rigidity during storing pe riod of different grain structures was analyzed to study the influence of different geometric parameters on the sensitivity, providing the structural integrity design of grain structure with the foundation for the theoretical analysis and the research.
