摘 要:为描述步兵战车自动炮连发射击精度变化规律,对自动炮首发射击弹丸起始扰动与次发射击弹丸起始扰动进行了仿真计算。基于移动荷载理论,以圆柱坐标系中弹丸径向速度为表征量建立了自动炮首发射击弹丸起始扰动仿真模型;在对首发弹丸射击后身管的剩余振动能量进行动力学仿真的基础上,应用身管膛线起始部单元在首发射击赋予的初始径向位移和初始径向速度作为身管的初始边界条件,建立具有身管初始扰动的弹炮耦合振动模型,对次发弹丸的起始扰动进行了仿真分析。仿真结果表明,首发弹丸射击后身管剩余振动能量大大增加了次发弹丸的起始扰动。The first shoot initial disturbance and the second shoot initial disturbance were simulated to describe the infantry combat vehicle automatic guns continuous shoot accuracy variation rule.The first shoot initial disturbance simulation model was found by the radial velocity in column coordinate system based on the moving load theory.The projectile-barrel coupling model with initial vibration was found and the second shoot initial disturbance was simulated by applying the initial radial displacement and the initial radial velocity of the origin rifle elements based on the firing dynamics simulation of the first shoot.The simulation results show that the second shoot initial disturbance is increased by the first shoot leavings vibration energy enormously.
