The Influence of the Diameter Ratio between Rigid Body and Particle on the Impact Strength Exerted on the Rigid Body Impacting Particles

Abstract:

Granular particles exist widely in the nature. The purpose of this paper is to research the impact interaction between rigid body and particles. The diameter ratio between rigid body and particle has the effect on the impact strength exerted on the rigid body impacting particles. In this paper, the same rigid body impacts respectively the particles with five different diameters. The effect of the diameter ratio is analyzed theoretically according to this simulation experiment. With diameter ratio increasing, the vertical velocity, mechanical energy and momentum of the rigid body increase, and the force exerted on the rigid body decreases.
