RUBBER DAMPER: Also known as tuned damper and acts as a dynamic absorber that absorbs torsional excitations and introduces a resonance that changes the system frequency.
Maximum rubber stress
Maximum heat load
Maximum rubber strain
RUBBER DAMPER: It consists of a central HUB which is mounted onto the crank nose, an INERTIA RING and an ELASTOMER ring in between the hub and the ring.
VISCOUS DAMPER: Also known as viscous shear damper or untuned damper as there is no elastic coupling or a specific stiffness or frequency. This damper is effective for the complete operating frequencies. It absorbs energy from the crank vibration and dissipates it in the form of heat energy.
