【摘要】：炮口振动是影响坦克行进间射击精度的关键因素,为了减小弹丸出炮口时的炮口振动,基于多体动力学的刚柔耦合及接触碰撞算法,建立了考虑多个结构非线性因素的坦克行进间刚柔耦合多体系统动力学模型。结合优化设计理论和方法,建立了坦克行进间射击炮口振动优化模型。通过径向基函数法与增广拉格朗日乘子法的结合,对坦克行进间射击炮口振动进行多目标优化设计。优化结果表明,弹丸出炮口时的炮口振动明显降低,优化方法是可行的,对于提高坦克行进间射击精度有一定的参考价值。通过改变车速以及路面等级对优化结果进行假设分析,说明了行进间射击优化的必要性。
[Abstract]:Muzzle vibration is the key factor that affects the firing accuracy of tank. In order to reduce the muzzle vibration of projectile out of muzzle, the rigid-flexible coupling and contact collision algorithm based on multi-body dynamics is used to reduce the muzzle vibration. The dynamic model of rigid-flexible coupling multi-body system with multi-structural nonlinear factors is established. Combined with the theory and method of optimal design, the optimal model of firing muzzle vibration was established. Through the combination of radial basis function method and augmented Lagrangian multiplier method, the multi-objective optimization design of firing muzzle vibration during tank moving is carried out. The optimization results show that the vibration of the muzzle is obviously reduced when the projectile is out of the muzzle. The optimization method is feasible and has certain reference value for improving the firing accuracy of the tank. By changing the speed and grade of the road, the hypothesis analysis of the optimization result is carried out, and the necessity of shooting optimization during the travel is explained.
