摘要
介绍 APFSDS及弹托干扰流场数值模拟中的网格生成方法及其应用 .利用等比数列网格生成技术 ,三维弧长生成技术以及拼接技术生成计算网格 .该方法具有简明、快捷的特点 .在临近物面的地方具有较好的贴体性和正交性 .在计算脱壳穿甲弹和弹托之间的干扰时 ,将弹托简化为带圆弧的楔形块 。
The grid generation and simulation methods on Armour Piercing Fin Stabilized Discarding Sabot (APFSDS) are introduced in this paper. The geometric progression technique and three dimension arc length technique are combined to form a new method. This method, which has close fitting and vertical property, is simple and effective. To calculate the disturbing between the projectile and the sabots, three sabots are simplified to cuneiform blocks, and the simulation result is satisfied.
