摘要
采用有限元法对固体火箭发动机药柱在高过载条件下的应力、应变和位移场进行三维线性粘弹性分析,得出了药柱在轴向和横向过载作用下的变形结果,为高加速固体发动机药柱结构设计提供参考。
The threedimensional linear viscoelasticity analysis of stress,strain and displacement fields for solid rocket motor grains under high overload is carried out using finite element method.The deformation results of propellant grains under axial and transverse overload are obtained.It is available for reference to the structure design of highacceleration solid rocket motor grains.
