Abstract

SOME IMPROVEMENTS IN THE DYNAMIC BEHAVIOR OF TWO-DEGREE-OF-FREEDOM PLANAR ARTICULATED OPEN-LOOP MECHANISMS CAN BE ACHIEVED BY MEANS OF ADAPTIVE BALANCING. AMONG THE BENE¯TS OF THIS TECHNIQUE ARE STATIC BALANCING, COMPLETE DECOUPLING OF DYNAMIC EQUATIONS AND ANNULLING THE REACTIVE MOMENT AT BASE. THE PROCEDURE TO ACCOMPLISH THESE GOALS CONSISTS OF ADDING MOVABLE COMPENSATION INERTIAS TO THE KINEMATIC CHAIN OF THE MECHANISM. THROUGH A PERFORMED SIMULATION, WE PROVIDE A COMPARISON BETWEEN A MECHANISM USING THE PROPOSED METHOD WITH AN UNBALANCED ONE.
