The effectiveness of particle damping for use on vertical surfaces

Particle damping has been shown to effectively reduce vibrations on complex structures and systems. Particle damping relies on intimate contact with the vibrating surface to be effective. Previous studies have focused on applying particle damping to horizontal structures where gravity ensures contact with the surface. However, many applications would make use of this damping technology on vertical surfaces. This paper investigates the added challenge and methodology of packaging particle damping for vertical applications and studies the variables that impact performance. The outcome will establish the key system parameters which drive performance and allow the capability to optimize particle damping effectiveness for these types of systems.
