| 摘 要： | 固体火箭发动机(SRM)推进剂药柱在立式贮存时要承受两种主要栽荷联合作用，即固化降温趋于平衡后的长期温差热载荷以及轴向的重力载荷作用。根据推进剂的材料特性以及不同的加载条件，采用线弹性理论，分别进行了SRM药柱在两种载荷作用下的三维有限元应力、应变计算，对药柱及其界面的危险部位重点进行了分析。

| Abstract: | Under vertical storage state of solid rocket motor (SRM), its propellant grain bears two main associate loads in a long period, that is, the heat load due to the temperature difference after the curing temperature tends to equilibrium state and self axial gravity load. By taking into account of the material properties and different loading conditions, and based on the linear elastic three dimensional finite element method, strain and stress of a SRM grain are calculated respectively under those loads, and some danger parts of grain and their interfaces are analyzed in special. |
