Torsional Vibration Damper Introduction

The engineering challenges of developing an OEM high performance engine are increasingly complex. Design requirements include generating more power from a smaller displacement, combined with airflow restrictions under the hood, while meeting long life durability.

All three are intertwined with controlling crankshaft torsional vibration. This back-and-forth oscillation of the crankshaft along its rotational axis is due to combustion forces. It is particularly critical at engine speeds where resonance can amplify the torsional amplitude forces. If left unchecked, torsional vibration contributes to engine failure.

While they may appear similar in design, Vibratech TVD driveline vibration dampers are different than crankshaft dampers.
