Based on the 2-D motion model of bullet penetrating gelatin, a function of the drag coefficient, the lift coefficient, the roll moment coefficient and the yaw damping torque coefficient derivative which is related to the bullet shape is established. Based on the 7.62 mm bullet, five kinds of bullets were designed for the penetrating experiment by changing the caliber of ogive, the ratio of tail contraction and the length-diameter ratio of cylinder. The model was calculated based on the Runge-Kutta method and the calculation is compared with the experiment. The result shows that these four coefficients can describe the effect of the bullet shape on the motion. It will provide theoretical bases for the ammunition design.

基于弹头侵彻明胶平面运动模型,建立了阻力系数CD0、升力系数CL0、翻滚力矩系数CM0、偏航阻尼力矩系数导数等关于弹头外形结构参数的函数。以56式7.62 mm普通弹为基础,分别改变其弧形部半径、尾部收缩比和圆柱部长径比,设计5种规格杀伤元,根据龙格-库塔法对运动模型进行数值计算,并对各杀伤元进行侵彻明胶实验。结果表明,4个系数能够准确合理地描述弹头外形结构对运动的影响,为弹药设计提供了理论指导。

基于弹头侵彻明胶平面运动模型,建立了阻力系数CD0、升力系数CL0、翻滚力矩系数CM0、偏航阻尼力矩系数导数等关于弹头外形结构参数的函数。以56式7.62 mm普通弹为基础,分别改变其弧形部半径、尾部收缩比和圆柱部长径比,设计5种规格杀伤元,根据龙格-库塔法对运动模型进行数值计算,并对各杀伤元进行侵彻明胶实验。结果表明,4个系数能够准确合理地描述弹头外形结构对运动的影响,为弹药设计提供了理论指导。

Based on the 2-D motion model of bullet penetrating gelatin, a function of the drag coefficient, the lift coefficient, the roll moment coefficient and the yaw damping torque coefficient derivative which is related to the bullet shape is established. Based on the 7.62 mm bullet, five kinds of bullets were designed for the penetrating experiment by changing the caliber of ogive, the ratio of tail contraction and the length-diameter ratio of cylinder. The model was calculated based on the Runge-Kutta method and the calculation is compared with the experiment. The result shows that these four coefficients can describe the effect of the bullet shape on the motion. It will provide theoretical bases for the ammunition design.
