Visco-elastic dampers consist of three parts as shown in Fig. 4.
(1) Lower cylindrical vessel
(2) Visco-elastic liquid in the vessel
(3) Cylindrical piston submerged in the visco-elastic liquid.
The cylindrical piston can move in the visco-elastic liquid three-dimensionally relative to the
movement of the lower vessel transferring vibration energy in this way into heat.
