| Along with the rapid development of world military technology, rocket weapon is endued with new mission namely that underwater launch. The environment of underwater is very complex. In this paper, the theory of ship seakeeping qualities is used to study three types movements of ship in wave, such as cross sway, longitudinal sway or vertical vibration. Then it adopts virtual prototype technology to carry out dynamic simulation.In this thesis, the underwater launcher of launch dynamics is researched. Simulation model of the underwater launcher is established by using the dynamic software, the actual model for the simulation and results analysis. The primary work of this thesis is as follow:Three-dimensional model of the launcher is established by using the software of CAD.Based on virtual prototyping technology, analyze the flexible body through modal analysis by using finite element analysis software. Then the model of rigid-flexible coupling launch dynamic is established.Analyzed the force and sport of the launcher underwater.The launcher for the simulation and results analysis when the launcher launched on the different angle and see complexion.In summary, this thesis's work provides foundation and theory gist for further researches about rocket launch underwater. And the research methods provide new thoughts and means for correlative research. |
