The mechanical properties of the device under different loading displacement different loading frequency and different loading times were studied by experiments. The results showed that the hysteretic curve of the device was relatively full and the energy dissipation was also good. The numerical simulation of the damping device was carried out by ABAQUS software the results were in accord with the experimental results. According to the experimental results the theoretical model of the damping device was established and the formulas and values of the relevant parameters were given.
