摘要

针对微重力环境下颗粒物质动力学过程表现出与常规重力场环境迥然不同特征,综述颗粒物质振动、碰撞、流动研究成果,分析总结颗粒动力学机制与特点,认为应加强对微重力环境下颗粒物质动力学行为机理研究,尽早提出微重力下颗粒动力学性质分析思路与动力学模型。

Abstract

In the twenty-first century, with human space activities becoming frequent, it takes our attention to dynamic behaviors of granular materials in space microgravity environment such as on the Moon and Mars. Due to the effect of micro-gravity environment, dynamic process of granular materials shows a series of characteristics which are very different from those in the conventional gravity environment. The paper summarizes research results of vibration, collision and flow of granular materials in microgravity environment. Dynamic mechanism and characteristics of particles are analyzed and summarized. Research on the dynamical mechanism of particles is proposed to be especially strengthened in the future study of granular materials dynamics in microgravity environment. It helps to bring forward some ideas of analysis on dynamic characteristics and dynamic models about particles under the microgravity as soon as possible.
