Application of Transfer Matrix Method of Multibody System in Launch Dynamics for Super-high Firing Frequency Weapon

" Metal storm " weapon system is regarded as a research object. Based on the multibody system transfer matrix method, a launch dynamical model of multibody system coupled with rigid and elastic body is established. A system characteristic equation is deduced and a system natural vibration characteristic is calculated. Accurate analysis of system dynamical response is achieved by constructing a system augmented eigenvector . Weapon system natural vibration characteristics, system dynamical response, interior ballistics parameter and projectile initial disturbance are obtained by numerical simulation. The simulation results can be used in dynamical design of the weapon.
