| Abstract: | Non Obstructive Particle Damping (NOPD) is a new developed damping technology since 1990s. It has been proved that the damping effect is very well and has been widely used in the domain of aviation. In this paper, research on the friction consumed energy of granula was discussed. The authors established theoretical models of friction consumed energy of granule in NOPD and numerical simulation and quantitative calculation of powder damper were done. At the end, relationship between friction damping and powder granule is found, it is very useful to the understanding of the damping mechanism of powder. |
