Antivibratory devices with phase reversal

Abstract

Abstract THE ENGINE AND TO SAID FRAME STRUCTURE AND ADAPTED TO CARRY THROUGHOUT ITS LENGTH AN INERTIA WEIGHT DISPLACEABLE THEREALONG FOR ADJUSTMENT PURPOSE, CHARACTERIZED IN THAT THE TERMINAL ELASTIC ELEMENTS CONNECTING SAID BAR TO SAID ENGINE AND TO SAID FRAME STRUCTURE HAVE ANISOTROPIC ELASTIC PROPERTIES DEPENDING ON THE STIFFNESS VALUES OF THE ELEMENTS ALONG TWO ORTHOGONAL AXES SUBSTANTIALLY PERPENDICULAR TO THE BAR AXIS. DEVIVE FOR DAMPING OUT A VIBRATION GENERATED BY AN ENGINE AND TRANSMITTED DIRECTLY TO THE FRAME STRUCTURE OR CHASIS THROUGH ELASTIC SUPPORT MEANS CONNECTING THE ENGINE TO SAID FRAME STRUCTURE OR CHASSIS, APPLICABLE NOTABLY TO MOTOR VEHICLES AND MACHINE TOOLS, AND ADAPTED TO INTRODUCE INTO THE FRAME STRUCTURE, AS NEAR AS POSSIBLE TO SAID ELASTIC SUPPORT MEANS, A SECOND VIBRATION OF SAME MODULUS BUT OF INVERTED PHASE IN RELATION TO THE FIRST VIBRATION, THROUGH A BAR RESILIENTLY CONNECTED BOTH TO
