The paper presents a prototype of an innovatory controllable torsional damper. The device is composed of Vacuum Packed Particles. Such structures are made of granular materials placed in a hermetic soft encapsulation. Generating so called underpressure inside the system changes global dissipative properties of the granular structure. The partial vacuum value is a convenient way to control physical properties of the granular structure. The authors introduce an original prototype of a torsional vibration attenuator. In the experimental part, preliminary experimental results are presented and discussed. To capture the real response of the device, a Bouc-Wen rheological model is adopted.
