Experimental Study of Particle Collision Damper for Vibration Attenuation
In cantilever beam system, through the experimental method to study vibration reduction mechanism of particle collision damper. The filling rate of particle damping agent in damper is 40%, added the damper with different diameter impacters and different kinds of particle damping agent in combinations ways, the cantilever beam system obtained the varying vibration reduction, according to the quality of vibration reduction, analyzed the joined impacters and particle damping agent influence of vibration attenuation rule. Experimental results show that damper added impacters and particle damping agent can dramatically reduce the maximum amplitude of cantilever beam system in resonant frequency, and can effectively restrain vibration of cantilever beam system.
