基于混合装药经典内弹道数学模型，建立了某榴弹炮内弹道 Simulink仿真模型。以两种火药的燃速系数和燃速指数为符合参数，以最大膛压及初速的仿真值与表定值的平均相对误差为目标函数，编写了利用遗传算法进行符合计算的 M文件，对内弹道参数进行了符合计算。结果表明，平均相对误差及各单项误差均可满足工程实际要求。该方法是对内弹道多参数符合计算的一种有益探索。

Based on the calculation model of mixed-charge interior ballistics, the simulation model of a certain type of howitzer was established by use of Simulink.Taking burning rate coefficient and index as the according parameters and taking average relative error of the simulation and table setting value of the maximum bore pressure and velocity obj ective function as the obj ective function,the M-files based on ge-netic algorithm were written,and the M-files were applied to the multi-parameter according calculation. The results showed that the average relative error and the individual error can be able to meet the practical requirements of engineering.This method is a kind of useful exploration for the multi-parameter accor-ding calculation method of interior ballistics.
