A particle damper is a device that acts as a passive damper that fills particles inside the enclosure in a variety of ways, resulting in energy dissipation due to collision and friction between the particle and the enclosure.
In this paper, an experimental study is carried out to establish the damping performance in a low frequency band by installing a particle damper on a single degree of freedom cantilever beam using a design of experiments. In this process, we analyze the influence of the parameters (excitation amplitude, mass ratio, particle size, gap size, enclosure diameter) affecting the performance of the particle damper.
Based on this, we try to optimize parameters of the particle dampers that can maximize attenuation of the system using MATLAB and MINITAB, and validate them through experiments.
