Structural dynamics modeling is a crucial technological task in the development of launch vehicles, load design, mechanical environment prediction, control system design, and POGO vibration suppression. Based on the evolutionary process of launch vehicles technologies, this paper reviews the development and application of structural dynamics analysis from four modelling approaches: the beam model, beam-shell hybrid model, the 3D model based on direct modeling and the 3D model based on model assembly. Additionally, this paper also covers the evolution of structural dynamic modeling technique and modal test in launch vehicle areas. Building on advances in numerical computation and the iterative refinement of launch vehicle methodologies, this paper further examines several emerging trends in the field several aspects, including efficient liquid-solid coupling computational technology, multidisciplinary dynamics analysis technology, dynamics analysis twin technology, and launch vehicle dynamics analysis technology based on artificial intelligence.
