Abstract

Abstract

In order to explore the impact of container structure on the motion characteristics of granular media in vertical vibrating grinding equipment, ADAMS-EDEM coupling simulation was used to simulate the motion characteristics of granular media during the vibrating polishing process. Firstly, the influence of container structure on particle motion characteristics is analyzed from the perspective of particle motion trajectory and velocity vector. Secondly, the influence of container structure on particle velocity and particle force is comprehensively judged from the depth direction and radial direction. Finally, the effectiveness of the simulation is verified through dynamic force test experiments. The experimental results show that the island-like structure aids the tumbling movement of particles but hinders circumferential movement. The movement of particles in the container with islands is more violent, and the average force of particles is greater than that of islands. The existence of the island structure does not change the basic law that the particle force gradually increases with depth, but it amplifies the force increase, particularly evident in the island container. However, the existence of the island structure basically does not change the trend of a gradual increase in particle force in the radial direction. The rationality of the simulation is verified by both sets of experiments.
- vertical vibration,
- coupled simulation,
- dynamic force sensor,
