摘要
以固体火箭发动机为研究对象，通过有限元分析方法，建立了发动机的三维全尺寸模型；依据随机振动理论和舰艇振动具体情况，计算出了在舰艇振动作用下发动机各组成部分的应力大小和分布规律，并比较了在不同振动作用下发动机的响应情况。
Taking solid rocket engine as the object of study, using the finite element analysis method, the full-scale model of the solid engine in three dimensional was established. Based on vibration theory, the stress size and distribution rule of the engine＇s each part during the action of naval vessel vibration were calculated, and the engine response situation was compared under the action of different vibration.
