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 theory of viscoelasticity, the finite element model of the column was established by using ANSYS finite element software to determine the key geometric parameters that affect the storage stiffness of the column. The analysis of the column stiffness during the storage period of different column structures was carried out to study the influence of different geometric parameters The sensitivity to the storage stiffness of the drug column provides theoretical analysis and research basis for the design of the integrity of the drug column structure.
