| Summary: | 碩士 === 國立中央大學 === 機械工程研究所 === 94 === This thesis investigates the dynamic characteristics of reduced scale solid propellant and fatigue life of solid propellant specimen under spectrum loading. The acceleration and strain responses were analyzed with finite element method and were compared to those of experiments. The outcome proved that the present FEM model is suitable and reliable.
Moreover, the fatigue experiments were enforced on a MTS machine, and the fatigue life of solid propellant under spectrum loading was analyzed with stress-life method and four kinds of frequency domain methods. The results show that stress-life method and “Narrow Band” method were more suitable for solid propellant.
