Simulation Of Launch Dynamics Of Shipborne Multibarrel Rocket

With its firepower, mobility and strong multi-purpose use, shipborne multiple launch rocket plays an important role in destroy barriers, land foreshore and so on.The shipborne multiple launch rocket system as an example is studied in the paper. The firing in move dynamic model of shipborne multiple launch rocket multi-rigid-flexible-body system is builded; the transfer equations, transfer matrices and overall equations, overall matrices of shipborne multiple launch rocket multi-rigid-flexible-body system firing in move are deduced with discrete time transfer matrix method of multi-rigid-body system; the force of rocket and rocket gun firing in move are analysed; the launch dynamic equations of rocket of shipborne multiple launch rocket system firing in move are deduced; the dynamics simulation procedure of shipborne multiple launch rocket system firing in move is developed; the simulation of the dynamic response, rocket movement in bore, rocket initial disturbance of shipborne multiple launch rocket system is carried out efficiently, and the simulation of firing in different velocity and different state of sea are got; the relationship between movement spectrum and wave spectrum are established in this paper; the theory and method of dynamics design of shipborne multiple launch rocket firing in move is provided.
