Multilayer circle metal plate damper (MCMPD) is a kind of new type isolator. It shows good performance under over loading, over speed, high temperature and low temperature working conditions to isolate vibration. The structural characteristic and the producing method of the damper are investigated in this paper. Dampers with different structural parameters were designed. Static and dynamic experiments of the specimens were explored. The hysteresis loops, response of vibration, transmissibility and resonant frequency of dampers with different thickness are obtained respectively. It is concluded from the experimental results that the thickness of the multilayer damper is the key parameter of influencing the characteristic of isolator. By changing the thickness of plates, the elastic damping and energy dissipation characteristics of damper can be varied. The results have great applicable value.
