METHOD TO CONTROL THE VIBRATIONS OF AN ARTICULATED ARM AND CORRESPONDING APPARATUS

摘要

Method to control the vibrations of an articulated arm (11) during its movement and use to carry out pumping operations of concrete, the articulated arm comprising a plurality of segments (12) articulated with respect to each other, each associated with a corresponding actuator (13).The method comprises at least a first step of detecting the temporal development and entity of the force which acts on at least said actuator (13) due to the vibrations, and a second step during which a processing and control device (31), as a function of said force, commands the drive of a hydraulic control circuit (30) connected fluidically at least to the actuator (13) to determine the damping of said force due to the vibrations.
