摘要:
针对在初速已知的情况下引信和弹药设计及性能、质量分析和试验数据评估与鉴别时弹道环境信息不足的问题,提出了应用1stOpt软件以有多号发射装药的155 mm加榴炮普通榴弹、122 mm榴弹炮普通榴弹和120 mm迫击炮弹为例,对内、外弹道学运动方程简化分析的方法。该方法对身管火炮膛压和最大射程落点诸元与初速关系进行了数值拟合,得到了具有较高精度的拟合公式,拟合公式精度较高,且便于应用。拟合结果表明,最大膛压与初速平方近似呈正比;最大射程及全飞行时间与初速近似呈正比;最大射程落速与初速的关系曲线近似为抛物线,初速无限增大,最大射程落速趋于恒定值;最大射程落角与初速近似呈线性关系,初速越大,落角也越大。
Abstract:
Aimed at the problem that when the initial velocity is known, lack reference information for ballistic environment for the design, analysis of performance quality, evaluation and identification of test data of fuze and ammunition, Taking 155 mm gun-howitzer projectile and 122 mm howitzer projectile and 120 mm mortar projectile with multi number propellant charge as an example, the software of 1st Opt was presented to simplify analysis of the interior and exterior ballistics equations of motion. The method carried out the relationship of the chamber pressure and the maximum range falling point firing data with the initial velocity of artillery by numerical fitting, the fitting formula with high precision was obtained. The fitting formula with high precision was easy to apply. The fitting results showed that the maximum chamber pressure was directly proportional with the square of the velocity of the initial velocity. The maximum range and the full flight time were directly proportional with the initial velocity. The falling velocity of maximum range was approximate to the parabola with the initial velocity, when the initial velocity increased infinitely, the falling velocity of maximum range tended to constant. The falling angle of maximum range was approximate to a linear with the initial velocity, the greater the initial velocity was, the bigger the falling angle would be.
