Effect of Random Factors of Charge on Interior Ballistic Performance

Abstract

In this paper, based on the sampling analysis of initial parameters of charge, such as propellant mass, arc thickness and combustible case mass, the influence of random factors on interior ballistic performance of charge is predicted by simulation calculation of random interior ballistic model. Firstly, the mathematical statistics analysis of initial parameters of charge is carried out to determine its distribution law. Secondly, the classical random interior ballistic probability model is constructed. The software is used to generate the initial parameters of large samples randomly, and a group of datum (7 rounds) is generated randomly from large samples. Through the model, carry out simulation calculation and analyze the influence of random factors on interior ballistic performance of charge.
