摘要



为获取最优的后坐阻力规律 以提高射击稳定性,基于多体系统动力学建模理论,建立了全炮动力学模型;以火炮射击时跳动量最小为目标,节制杆各圆锥段直径为设计变量,基于优化设计方法对优化问题进行了求解。优化结果表明:最大后坐阻力和火炮跳高都小于优化前,后坐阻力曲线更加平缓,火炮射击稳定性得到明显改善。




Abstract

Abstract: In order to obtain the optimal recoil resistance force to improve firing stability of gun, the dynamic model of overall gun system based on multi-body system dynamic modeling theory was built. By defining the minimal jumping height of during the firing period as optimal objective and the diameters of taper segments of control rod as design parameters, the problems are resolved through optimal design method. The optimized results indicate that the maximal recoil resistance force and jumping height are reduced after optimized. The recoil resistance curve is more smooth, at the same time, the firing stability of gun system is considerably improved.
