FIELD: vibration damping.
SUBSTANCE: vibration dampers of the working tool of a cable robot, namely to a cable system with a passive vibration damping. The cable system with a passive dynamic vibration damper contains a supporting structure, a mobile platform suspended on several cables on the supporting structure, while it has a control unit that is connected to the actuators for moving the cables and is designed to control these actuators for changing the position and orientation of the mobile platform, and a passive vibration damper made in the form of a spring-loaded movable mass placed on a vertical axis in the lower part of the mobile platform and configured to perform rotational movement around the vertical axis, moreover, a damping spring is placed between the mobile platform and movable mass.
EFFECT: increasing the efficiency of damping of torsional vibrations.
