Viscous dampers ISOSISM FD

The Isosism FD fluid viscous damper is a restraint with a response characteristic that is a function of the velocity with high energy dissipation; the device applies an insignificant force for small velocities (thermal movement, etc…) while it reacts with the designed target force for high velocities (dynamic loads, earthquake, etc..).
The device can be designed with a wide range of target forces and displacements. The Isosism FD fluid viscous damper has been design and tested for extreme conditions: velocities up to 1 m/sec and temperatures from –10 to 55 degrees Celsius.

The Isosism FD devices have the following advantages:

- Low maintenance, all the hydraulic parts of the circuit are inside the device and so are protected

- Possibility to fit any force and displacement required by the designer

- Immediate response, even with very small displacements

- Response stability with temperature

- High damping
