Abstract

The invention includes systems having a cover attached to a frame, and a transmission unit with a rotational device connected to or part of the frame. The cover is mechanically connected to the at least one rotational device. A vibration dampening unit mechanically connected to the transmission unit such that translational movement (e.g. vertical movements) of the cover causes rotational movement of the rotational device. The rotational movement is, in turn, transmitted to the vibration dampening unit via the transmission unit. Preferably, the vibration dampening unit is a passive unit and also a resistance force modulated vibration dampening unit. The invention also includes methods for dampening vibrations on a load which includes converting translational movement of a load to rotational movement in a transmission unit, the transmission magnifies the displacement and speed of the rotational movement, and then transmitting the rotational movement to a vibration dampening unit, which dissipated the vibrational energy.
