Application of Particle Damping in Vibration and Noise Isolation of Drum Brake

Abstract:

Particle damper comprises granular particle enclosed in a container within a vibrating structure. It may be applied in extreme temperature environments where most conventional dampers would fail. In this paper, the feasibility of an application of particle damping to the noise and vibration control of a drum brake is analyzed. A coupling simulation algorithm based on the discrete element method and finite element method is presented. This method makes it possible to consider parameters of particle damper such as the particle size, ratio and particle material and so on. The validity of this numerical method is examined by a comparison of the experimental results. And the results show that the presented particle damping is effective and the analyses of dynamic feature of a drum brake with particle dampers are reasonable.
