摘　　要：本文首先按照火箭的不同型号,综述了国内外全箭模态分析及试验验证的进展情况;然后,从蒙皮加筋圆柱壳结构动力学建模、液体推进剂动力学模拟、局部振型斜率预示三个方面,综述了火箭动力学建模技术进展;最后根据火箭动力学发展需求,对后续研究提出了一些建议.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.
