APPARATUS AND METHOD FOR CONTROLLING A VIBRATORY TOOL

摘要

An apparatus and a method are provided for increasing the density of a compactible material while continuously evaluating the density of the maternal. The evaluation of material density is carried out by calculating the total of the static, dynamic and centrifugal forces applied by a vibrating tool to the compactible material. The total applied force calculation includes measuring the vertical acceleration of the material contacting member and the position of an eccentric mass mounted on the material contacting member. The acquisition of these parameters is carried out simultaneously, and the calculation of the dynamic and centrifugal forces is made when the material contacting member is at its lowest position.
