摘要
以发动机翼柱型装药为研究对象,分析了发动机装药在摇摆载荷作用下所受的横摇和纵摇力矩,并利用有限元分析法计算了巡航期内发动机装药在摇摆载荷作用下的应力和应变变化情况,通过不同路经下的应力应变分析得出最大应力点以及危险部位,应用药柱破坏判据对发动机装药可靠性进行了判断,得出:在巡航期内摇摆载荷作用下发动机装药结构不会发生破坏。
Taking the fin-slot of SRM as the research object, the rolling and pitching moments under the swing load were analyzed; the stress and strain of fin-slot of SRM under the swing load were calculated by method of finite element analysis in the cruise period. To ana- lyze maximum stress and dangerous position, the structural integrity of fin-slot of SRM was evaluated with failure criterion. The result indi-cates the structural integrity of fin-slot of SRM would not be destroyed under the action of rolling and pitching in cruise period.
