摘　　要：利用单一装药经典内弹道数学模型,用MATLAB软件编写火炮内弹道程序,得到内弹道各特征量如弹丸速度、火药气体平均压力、火药气体温度随时间变化规律,并且对内弹道参数如次要功系数、火药力、余容进行了计算。仿真结果与实验结果基本吻合,验证了仿真结果的正确性。By using a single charge classical interior ballistic mathematical model,the ballistic program of artillery was written with MATLAB software,and the result of the internal ballistic was obtained,such as the speed of the projectile,the average pressure of the gunpowder gas and the change of the temperature of the gunpowder gas with time. The internal ballistic parameters such as the secondary work coefficient,the power of gunpowder work and the covolume are calculated. The results show that the simulation results are in good agreement with the experiment results,and the correctness of the simulation results is verified.
