基于全膛烧蚀磨损特征的火炮内弹道仿真研究
|
摘要
为提高烧蚀火炮内弹道仿真精度,在文献[1]火炮烧蚀内弹道理论基础上,保持火药几何燃烧定律、火药燃速定律和体现起始部膛线烧蚀的弹丸起动压力方程不变,通过对变炮膛截面积、变药室容积、弹后烧蚀容积增量等全膛烧蚀磨损特征的分析和计算,建立体现全膛烧蚀的弹丸运动方程和内弹道基本方程,从而建立烧蚀磨损内弹道模型。借鉴经典内弹道诸元解算方法,导出烧蚀磨损内弹道模型解算方法。以某火炮试验数据为例进行仿真烧蚀磨损内弹道计算,仿真结果表明:初速仿真值与试验值误差为0. 9%,能够满足火炮工程实践3%的仿真误差要求;仿真精度优于文献[1]的火炮烧蚀内弹道方法,证明了所建立的烧蚀磨损内弹道模型和诸元解算方法是正确的,可用于烧蚀磨损火炮身管寿命预测。
In order to improve the simulation precision of artillery interior ballistics,on the base of the artillery erosion interior ballistics theory in Ref. [1],the kinetic equation of projectile and the basic equation of interior ballistics are set up by keeping the equations of the variable projectile starting pressure,and the geometric combustion law and burning rate law of gunpowder unchanged,and analyzing the fullbore erosion wear characteristics of artillery,such as variable bore sectional area,variable chamber volume and volume increment after body,and then an interior ballistics model based on the whole-bore erosion wear is established. The resolving method of interior ballistics is derived. The certain artillery test data are computed through simulation. The simulated results demonstrate that the error simulated and test velocities are less than 0. 9%,which satisfies the requirement of 3% simulation error of artillery engineering practice. The proposed method is better than the artillery erosion interior ballistics theory in Ref.[1]. The result proves that the proposed interior ballistics model and resolving method have higher simulation precision,and could be used for the prodiction of artillery barrel life.
