Abstract: Particle damping is a damping technique that has found wide applications in engineering systems. It is a form of damping where the energy dissipation is achieved through the motion of small particles within a cavity. This technique has several unique features that make it an attractive option for many engineering applications. Cantilever beam with FFT analyzer is used to find the response parameters. The readings are taken with varying cavity dimensions, size of ball, packing ratio and ball material. The readings in the form of acceleration are noted by varying one experimental parameter. From the experimentation it is found that 24 mm diameter and height 37 mm cavity with 50% Packing ratio is effective for the applied experimental set-up.
