摘要
为获取最优的后坐阻力规律FR(t)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。
In order to obtain the optimal recoil resistance force to improve firing stability of a gun,the dynamic model of an overall gun system based on dynamic modeling theory of a multi-body system was built.Defining the minimal jumping height during firing as the optimal objective and the diameters of taper segments of the control rod as design parameters,the optimization problem was resolved with the optimal design method.The optimized results indicated that the maximal recoil resistance force and the jumping height are reduced after optimization; the recoil resistance curve is more smooth; meanwhile,the firing stability of the gun system is considerably improved.
