The platform is subjected to a dampening force, which is a function of the rate of alteration of >=1 displacement component of the rolling movement. The sepd. of an undesirable movement of the platform is scanned, and a dampening control force is applied onto it, this being a function of the scanned speed, and is opposed to it. For scanning, sensors are provided, the output valves of which act onto a control unit, which in turn acts onto the platform. The sensors are formed, so that the vertical speed of lifting components of undesired movements is measured during wave periods, which corresponds to the resonance frequency of the structure. |
