Welcome to Vibratech TVD's company blog.  Let's begin by introducing the fundamentals of viscous damper technology. Feel free to use the comments section below to provide feedback and recommendations for future blog posts.

 


 

Part 1:  What Is A Viscous Damper?

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

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.
