Dissipation Behaviors of Vibrated Granular Balls in Different Gravity Environments
The dissipation behavior of granular balls in a quasi-2D closed container subjected to vertical vibration is studied by means of discrete element method in this paper. Four universal granular phases playing high damping effect are finalized by simulating the gravity environments of Earth, Mars and Moon, respectively. Based on the commonality of dense granular clusters in the four high damping granular phases, the ideal dissipation behavior of granular balls in the quasi-2D closed container is indicated. Moreover, the optimal damping mechanism of granular balls in the quasi-2D vibrated closed container is further revealed by analyzing the differences of kinetic energy and potential energy of vibrated granular balls in the three different gravity environments. This study lays a foundation for maximizing the damping effect of vibrated granular materials with constant mass by controlling their dissipation behavior, which provides a new idea for the universal design of granular damping structures in engineering practice.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
