| Abstract: | First in this paper, based on different kinds of launch vehicles, domestic and overseas overall modal analysis and experiments verification are respectively reviewed. Then dynamics modeling techniques are respectively summarized from three directions, such as dynamics modeling of cylindrical shell-stiffened, dynamics simulation of liquid propellant, prediction methods of local mode shape-slope. Finally, further research directions are suggested based on the development needs of structural dynamics of launch vehicles. |

| Keywords: | overall model experiments verification cylindrical shell-stiffened liquid propellant mode shape-slope |
