Investigations of Particle Impact Damper with Elastic Support

Compared with traditional impact damping devices, particle impact damper under elastic support, a new impact damper with double damping structure, has better damping performance. For the purpose of further studying its damping effects on cantilever beam, this paper comes up with both the dynamic model and the movement differential equation of the particle impact damper system with elastic support, and stimulates the damping effects of cantilever beam under the influence of this device. Simultaneously, based on experiments on the damping effects of the particle impact damper with elastic support under five different stiffness conditions, it is concluded that: results from the theoretical calculation basically agree with those from experiments, which verifies the reliability of the calculation model of the particle impact damper with elastic support built by this paper.
