Particle Impact Damping in Two Dimensions

摘要：

Particle impact damping (PID) is a technique of achieving high structural damping with small metallic particles embedded within a cavity that is attached to vibrating structure.This is a highly non-linear damping mechanism in which energy dissipation is primarily related to friction and impact phenomena.In this work a simple yet detailed analytical model is presented to study PID in two dimensions under transient vibrations.Normal as well as oblique impacts are considered.The effect of cavity size and acceleration amplitude on PID is studied and the results are supported by experiments.Fairly good agreement is found between the theory and the experiment.
