摘要为了研究火炮系统结构参数对弹丸膛内运动和炮口扰动的影响，通过引入虚拟体，提出了一种充分反映弹炮间相互作用的火炮动力学建模方法，推导了含虚拟体项的自行火炮刚柔耦合动力学方程；同时，以某型履带式自行火炮为例，引入多目标优化算法，建立了以弹丸和炮口初始扰动为目标函数的火炮系统多目标优化设计模型，获得了在相同射击条件下试验测试数据和仿真计算结果的对比曲线，以及结构参数的优化结果。分析表明，采用该方法建立的模型能较真实地反映火炮系统的动态响应特性和弹丸的膛内运动规律，且在考虑弹丸与柔性身管接触碰撞的前提下实现了弹丸和火炮运动的多目标优化设计，可以为自行火炮的发射动力学研究提供一定参考。

Abstract：In order to investigate the influence of the gun structural parameters in the bullet motion and muzzle disturbance, a model considering the bullet-barrel interaction was set up by introducing virtual substances. The rigid-flexible coupling dynamics equation of the self-propelled gun system was derived. Taking a tracker self-propelled artillery for an example, the system optimization model was obtained in which the initial disturbances of the muzzle and the projectile were regarded as the objective function. As a result, the comparative curves between the experimental data and the calculation result under the same firing condition were obtained, so the optimization result of structural parameters was. The result shows that this model can reflect truly both the system dynamic response and the bullet motion regularity. Besides, the multi-objective model was optimized on the premise of considering the bullet-barrel contact, which provides reference for the launching dynamics research of the self-propelled gun.

Key words： virtual substance projectile-barrel rigid-flexible coupling multi-objective optimization
