The characteristics of debris clouds produced by hypervelocity impacts are simulated and analyzed by smoothed particle hydrodynamics (SPH). The variational laws of the diameter of holes, the width of debris clouds, the cumulative percentage of fragments, the dimensionless momentum MD/M0 and the residual velocity are given. By fitting computational data, the cumulative percentage of fragments as a function of the fragment mass and the impact velocity is presented. The computational results show that the function agrees with SPH results very well.

采用光滑粒子流体动力学(SPH)方法对不同形状的弹丸超高速碰撞形成的碎片云特性作了模拟分析,给出了靶孔直径和碎片云宽度随碰撞速度的变化规律、同一速度下不同形状的弹丸累积碎片分布规律、同种弹丸不同速度下的累积碎片分布规律、弹丸初始半径范围内的碎片云无量纲向前总动量MD/M0随膨胀距离LE的变化以及碎片云前端速度的变化规律等。通过数据拟合,进一步给出了累积碎片百分数与碰撞速度和碎片质量的近似函数关系,计算表明该函数关系与数值结果吻合得很好。

采用光滑粒子流体动力学(SPH)方法对不同形状的弹丸超高速碰撞形成的碎片云特性作了模拟分析,给出了靶孔直径和碎片云宽度随碰撞速度的变化规律、同一速度下不同形状的弹丸累积碎片分布规律、同种弹丸不同速度下的累积碎片分布规律、弹丸初始半径范围内的碎片云无量纲向前总动量MD/M0随膨胀距离LE的变化以及碎片云前端速度的变化规律等。通过数据拟合,进一步给出了累积碎片百分数与碰撞速度和碎片质量的近似函数关系,计算表明该函数关系与数值结果吻合得很好。

超高速碰撞  /  碎片云  /  光滑粒子流体动力学

The characteristics of debris clouds produced by hypervelocity impacts are simulated and analyzed by smoothed particle hydrodynamics (SPH). The variational laws of the diameter of holes, the width of debris clouds, the cumulative percentage of fragments, the dimensionless momentum MD/M0 and the residual velocity are given. By fitting computational data, the cumulative percentage of fragments as a function of the fragment mass and the impact velocity is presented. The computational results show that the function agrees with SPH results very well.
