The Non-obstructive Particle Damping (NOPD) has been widely used as an effective passive damping technique. However, the understanding of energy dissipation mechanism and meso-scale behaviors of granular system in NOPD is not in-depth enough. In this paper, the damping effectiveness of NOPD was analyzed combining with the motion modes of granular system and the energy dissipation mechanism was illustrated at the meso-scale. The results shows that the different motion states and meso-structure leading to the variations of the damping effectiveness. Generally, the NOPD has the optimal damping effectiveness in the buoyancy convection state. The purpose of this paper is to provide better understanding and theory support for the design and application of NOPD.
