Description

Technical Field

[0002] Vibration drive is one of the commonly used drive methods for studying the motion behavior of particle systems in space experiments. Generally, vibration is applied to the experimental chamber in a certain direction. The particles near the side walls of the experimental chamber will gain speed when colliding with the wall. Then, through the collision of these "hot" particles with other particles, the kinetic energy is transferred to other particles in the system. By obtaining the motion trajectory and energy transfer characteristics of the particles, the dynamic behavior of the particle system is further studied.
