摘要
针对astroblaster多体碰撞过程,运用分离碰撞模型和同时碰撞模型进行分析,对分离碰撞模型给出了计算公式,对同时碰撞模型则进行了计算机模拟.首先,采用刚性分离模型研究二体、三体碰撞物体的运动速度、弹射高度与碰撞体质量之间的关系,得到弹射高度最大化的条件;其次,利用计算机模拟建立同时碰撞模型,研究物体弹性性质对碰撞的影响,分析物体在碰撞时加速度的变化情况,给出在同时碰撞模型下弹射高度最大化的条件.
This article focuses on the principle of astroblaster and discusses the relationship between reboun- ding height and relative parameters in terms of separate collision modeling as well as spontaneous collision modeling with the support of theoretical calculation and numerical simulation Firstly, separate collision modeling is applied to analyze how the mass distribution affects the final velocity and rebounding height in the 2-ball, 3-ball and N-ball collision model. The conditions for maximum elevation are concluded for separate collision modeling. Secondly, spontaneous collision modeling is presented. This modeling involves the effect of elasticity on different objects. The change of acceleration of the objects in astroblaster is also mentioned. The conditions for maximum elevation are concluded for spontaneous collision modeling.
