Dynamics Analysis Of A Certain Type Of Ground Launchers And Missiles Out Of Tube Speed Control Simulation

Based on reasonable simplification to one type of missile launching system, this dissertation builds an accurate model and finishes dynamical analyses by use of UG(Unigraphics) and ADAMS(Automatic Dynamic Analysis of Mechanical Systems) .This dissertation analyses concretely that the outspread processes of the missile launching device in different drive way, the effect to the outspread processes by changing crane's parameters, the effect to vertical ejecting launch of the missile by changing parameters of the low-pressure-chamber and parameters of the crane, and the effect to dynamic characteristics of the missile launching device by changing the mass characteristics of the key parts. This dissertation lays emphasis on the changes of the intensity of impacting loads and the change of missile's movement parameters in different launching phases. The analysis results could be regarded as designing reference of new type of weapon system and the dynamical parameter model could be used to do more deep analyses according to different design needs. Based on the results from simulating the ejecting device's interior ballistics of the certain missile, the sample database consisting of the missile's velocity as it leaving canister and relevant initial height of the low-pressure-chamber is built. The samples are trained by BP neural network. At last, depending on this neural network, a numerical control device is designed to control the missile's velocity as it leaving canister, and this numerical control system is simulated in the dynamic simulating tool-SIMULINK of MATLAB. The design will give new ideas and suggests to works of developing new weapon system or improving these existed weapon systems.
