摘　　要：针对某混合装药火炮的内弹道性能优化问题,提出了一种基于混合策略的改进萤火虫算法。建立了该混合装药火炮的经典内弹道数学模型,考虑到标准萤火虫算法易于陷入局部最优,且全局寻优能力较弱的缺陷,因此采用了一种基于混合策略的改进萤火虫算法。通过3种优化方案分别对该混合装药火炮进行内弹道的性能优化对比,结果表明:改进后的萤火虫算法体现了较为突出的优越性,收敛效果较好,在满足最大压力的约束条件下,采用改进的萤火虫算法提升了该火炮的初速,相比优化前,炮口速度能提升26 m/s左右,该结果进一步说明了改进萤火虫算法在内弹道性能优化中的可行性和适用性。Aiming at the optimization of the interior ballistic performance of a gun using a mixed charge,an improved firefly algorithm based on a hybrid strategy is proposed.Firstly,the classical interior ballistic mathematical model of the gun was established.Then considering the defects of the standard firefly algorithm that it is easy to fall into local optimality and the global optimization ability is weak,an improved firefly algorithm based on a hybrid strategy was adopted.The interior ballistic performance of the gun was optimized through three optimization schemes.The results show that the improved firefly algorithm embodies more prominent advantages and has a better convergence effect.Under the maximum pressure constraint,the improved firefly algorithm can greatly increase the muzzle velocity of the gun,the muzzle velocity can be increased by around 26 m/s compared to that before optimization.The result further illustrates the feasibility and applicability of the improved firefly algorithm in interior ballistic performance optimization.
