Fluid Viscous Dampers

Fluid Viscous Dampers are cylinder/piston devices that exploit the reaction force of silicone fluid forced to flow through an orifice and/or valve system. The typical force-velocity law is non-linear, i.e. F=Cvα, where α =0.15, F is the force, C is the damping constant and v is the velocity. Different values of the α exponent can be provided on request.
