火炮内弹道性能直接决定火炮的首发命中率和首群覆盖率,为提高高膛压滑膛坦克炮射击效果,补偿因烧蚀磨损造成的内弹道性能下降,在分析火炮烧蚀磨损内弹道学理论的基础上,建立了基于烧蚀磨损的滑膛坦克炮内弹道数学模型和基于MATLAB/Simulink的内弹道仿真模型。对滑膛坦克炮内弹道进行了数值模拟,得到了不同烧蚀磨损情况下火炮内弹道性能的变化曲线,将仿真结果与实验数据进行了分析比较,结果表明:仿真结果与实验数据基本吻合。验证了模型的可行性,仿真结果可为磨损火炮的内弹道性能修正提供参考,同时,基于Simulink的内弹道仿真模型的建立更有利于后续模型的工程化应用,可实现与硬件设备的紧密结合,为烧蚀磨损火炮内弹道性能的研究应用提供了新思路。

The interior ballistics performance of the artillery directly determines the first-round-hit probability and the first group coverage probability of the artillery ammunition.In order to improve the shooting effect of the high-pressure smooth bore tank gun and compensate the reduction of internal ballistic performance caused by erosion and wear,this paper establishes an internal ballistic mathematical model of the erosion smooth bore tank gun and a simulation model based on MATLAB/Simulink.by analyzing internal ballistic theory of artillery erosion and wear.The numerical simulation of the interior ballistics of the smooth bore tank gun is carried out,and the variation curves of the interior ballistic performance of the tank gun under different ablation wear conditions are obtained.The simulation results are compared with the experimental data,and the results show that the simulation results are basically consistent with the experimental data,which verifies the feasibility of the model.The simulation results provide a reference for the correction of the interior ballistics performance of the erosion artillery.And it is more conducive to the subsequent model engineering application,and can be closely integrated with the hardware equipment,which provides a new idea for the research and application of the erosion and wear gun.
