Particle damping is a very promising passive damping technique, however, it is still rarely used in technical applications due to its complex dimensioning. An experimental model is developed in order to investigate the energy dissipation of the dampers regardless of the underlying structure. The testbed consists of a particle box with a free‐free boundary condition which is excited by an acceleration controlled shaker. The loss factor and the energy dissipation are obtained via the complex power. The particle damper can be analyzed over a wide frequency and acceleration range. Different particle numbers are used showing the high potential of particle dampers for different excitation ranges.
