The MC and MCL type fluid viscous damper (FVD), is a displacement dependent device.
The behaviour of the device depends on the speed according to the following law: “F = C x v x a“
Where:
Its behaviour is symmetrical to the intermediate position, both in terms of reaction and displacement.
This way of operating is allowed by the presence of a piston inside the steel liner that divides two chambers containing hydraulic fluid and connected via a calibrated valve.
Two spherical hinges connect it to the structure, allowing rotation around any axis. The device acts like a connecting rod, only able to transmit forces along its axis.
