Abstract

In order to solve the problems of weak processing,low visualization and no storage mechanism of the original projectile mass and quantity distribution prediction calculation software,it was reconstructed and redeveloped.Through the adoption of object-oriented methods and advanced development tools and technologies such as Python,Pycharm,PyQt,etc.,the new version of the software improves the calculation accuracy,expands the scope of prediction,and advanced system architecture,providing the underlying technical support for the subsequent intelligent learning development such as machine learning.Verifying the implementation of each predictive model algorithm,the average relative error of the number of effective fragments/quality and historical experiment results is less than±3%; the relative error of the number/mass of killing fragments and historical experimental results is less than±1.9%.

Key words： projectile fragment; quality and quantity distribution; distribution prediction; object-oriented; Python
