Abstract

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 analyze maximum stress and dangerous position, the structural integrity of fin-slot of SRM was evaluated with failure criterion. The result indicates the structural integrity of fin-slot of SRM would not be destroyed under the action of rolling and pitching in cruise period.

Key words： fin-slot of SRM; swing load; structural integrity
