微重力下颗粒物质动力学性质综述
Review on some dynamical properties of granular materials under microgravity
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.
