摘要
针对航天器的碰撞毁伤程度与超高速斜碰撞所产生碎片云的形态的关系,利用光滑质点流体动力学(SPH)方法研究了超高速斜碰撞所产生碎片云的形态.主要分析了碰撞参数,如弹丸速度、靶板厚度、弹丸直径对碎片云形态的影响.仿真结果表明,二次碎片云的膨胀速度以及膨胀尺寸随碰撞速度和弹丸直径的增加而增加,随靶板厚度的增加而减小.
Considering the relations between the damage of space vehicle suffered in hypervelocity oblique impact and the configuration of the secondary debris cloud, Smoothed Particle Hydrodynamics （SPH） technique is applied to study the configuration of the debris cloud generated in a hypervelocity oblique impact. Relations between the configurations of the debris cloud and the impact parameters, such as impact velocity, projectile diameter and plate thickness are analyzed. The results show that the expanding velocity and dimension of the secondary debris increase with the increasement of the impact velocity and the projectile diameter, and decrease as the plate thickness is increased.
