| Abstract |
As a complex beam structure system, the barrel vibration during firing directly affects the system stability and projectile hitting accuracy. In this paper, an efficient calculation method is proposed for the dynamic response of the complex beam structure system. Based on the extended Hamilton’s theorem, the kinetic equations of the axially moving beam under the action of moving mass are
established and solved; the model of the cradle-barrel-projectile beam structural system is established,
and the kinetic response is numerically calculated by considering the interaction relationship of the
relevant structures during the firing process of the artillery; the kinetic tests of the artillery firing muzzle are designed and completed. The results show that the proposed method outperforms the existing
commercial software in solving the dynamic response of complex beam structure systems and has
higher computational efficiency while ensuring the accuracy of the calculation. This paper provides a
theoretical reference for the rapid calculation and prediction of the dynamic response of artillery firing
and an efficient calculation method for the dynamics of complex beam structure systems. |
