摘要/Abstract

摘要： 研究射弹的运动姿态变化规律对攻击和防护都有十分重要的意义。研究了弹丸受到偏转力作用下的动力学过程，分析弹丸各运动参数的改变规律；深入分析弹丸撞击并侵彻金属圆锥体现象，建立了实心圆锥体对侵彻弹丸的导偏效果预测模型；分析比较空心金属圆锥体与实心金属圆锥体对弹丸导偏过程的差异，利用调整系数对实心圆锥体导偏效果预测模型进行修正，得到了空心圆锥体导偏效果预测模型；利用试验数据对空心圆锥体导偏效果预测模型进行了计算验证，结果表明吻合情况良好。

Abstract: The study on the change rule of projectile attitude is important in improving either the attacking capability of projectiles or the protective capability of projects. The dynamics process of projectile subjected to deflecting force is discussed, and the change rule of motion parameters is analyzed. An in-depth study is given to the phenomena of which a projectile strikes and penetrates the metallic cone, and a mo-del for forecasting leading-yaw performance of solid cone is established. The difference between yawing processes of solid cone and hollow cone is analyzed, and a model for forecasting yawing performance of hollow cone is founded with a correction modulus applied on that of solid cone. The experimental verification of the model for hollow cone proves that the computational results are in good agreement with the experimental results.

Key words: ordnance science and technology, metallic cone, penetrating projectile, yawing, prediction model
