What Is A Viscous Damper?

Posted by Brian LeBarron on Jan 22, 2015


A viscous damper is a fundamental component to create durability and efficiency in a powertrain system by reducing torsional vibration.

Viscous Dampers - Born From Necessity

Houdaille (later renamed to Vibratech TVD) invented the technology in 1946 (view company history) to reduce the risk of crankshaft failure being experienced in diesel powered off-highway equipment. While other torsional damping devices existed at the time, soon the reliability of a viscous damper made it the preferred choice of design engineers and purchasers. They can be found today protecting business critical equipment in the off-highway, rail, oil and gas, power generation, marine, military and over-the-road trucking domains. In addition, they are commonly used at the automotive OEM level in exotic sports cars and light-duty diesel trucks, plus grassroots to professional racing applications.


Today’s Challenge

Today design engineers at engine, vehicle and equipment manufacturers are challenged even harder to deliver emissions-compliant, quieter and more fuel-efficient powertrains without sacrificing performance and reliability. The use of sophisticated turbochargers, high-pressure fuel injection and elevated mean effective pressures put an even greater and destructive torsional vibration force into the system.
