Determination of Maximum Damping Efficiency based on Electric Drive Vibrations of Elastic Mechanisms

The main factors that determine maximum values of elastic mechanical vibrations of operating machines with an electric drive were detected. The efficiency of different ways of vibrations passive damping of elastic mechanisms was reviewed. The conditions were determined and recommendations about the choice of parameters of electric drives ensuring minimum dynamic efforts in springy elements of mechanical gears were given. It was found that damping of vibrations in the elastic mechanisms caused by changing of disturbing effort by the electric drive is the most effective if the resonant frequency of mechanical vibrations is in the range of frequencies of electric drive dropping. The estimation of marginal efficiency by the electric drive of vibrations in elastic mechanical gears has been performed, the areas of reasonable application of damping devices and the electric drive for the reduction of dynamic efforts in springy elements of mechanical gears were defined. The practical implementation of the proposed recommendations has been carried out for the MP100 type balanced manipulator.
