Study on the Method of Particle Damping Loss Factor Experiment

Abstract:

Particle damping (PD) is an emerging technology of efficient vibration control method. However, there are still limited applications in mechanical engineering due to the complexity of damping mechanism. In this paper, basing on the comprehensive studies about gravel particle damping and comparing the existing methods, the steady-state flow method is adopted as the measurement method of particle damping loss factor. Then using this method to measure the loss factor within the 500 Hz sand particle dampers, and the experimental results verify the accuracy of this test method, test results, as well as the superiority of particle damping in vibration.
