The optimal design of exterior ballistic is a complex nonlinear multi-constraint problem.Most of the traditional optimization methods belong to local optimization methods,and there are some limitations in using these methods to optimize the exterior ballistic design.The intelligent optimization algorithm can realize global optimization and has advantages in dealing with complex nonlinear multi-constraint optimization problems.Taking the optimal design of a small caliber anti-aircraft gun projectile as an example,the mathematical model of optimal design of exterior ballisticwas established.The genetic algorithm based on binary coding and floating-point coding was improved by niche technology,and the selection of key parameters of genetic algorithm was analyzed.The simulation results show that the improved genetic algorithm has a good effect on the exterior ballistic optimal design of small caliber anti-aircraft gun projectile.
