考虑弹丸与身管轴向运动耦合的火炮系统时变动力学分析
The research of artillery time-varing dynamics system considering thecoupling between bullet’s moving and barrel’s axial movement
The artillery system is simplified to an axially moving cantilever beam under the action of a moving mass. The axially moving beam’s vibration control equation that considering beam’s tension was obtained based on the Bernoulli-Euler theory and Hamilton principle. Using assumed mode method and Galerkin Discrete method to solve this vibration control equation. The difference between considering and unconsidering axial movement in artillery model was be analyzed by by numerical simulation. And considering the influence of initial disturbance on transverse displacement of the beam’s top.
