Automotive lightweighting is an industry-wide challenge, and that challenge increases when noise, vibration, and harshness (NVH) goals are considered.

Excessive vibrations can

  • Introduce disruptive noise that causes discomfort or even injury to passengers
  • Shorten product life
  • Result in damage to attached materials or components

Our solution is Countervail - a true composite materials product line that can address NVH requirements at minimal weight and has been engineered to require no changes in tooling and manufacturing procedures for implementation.

DYNAMIC MOBILITY REDUCTION

Lightweight, stiff structures can exhibit complex frequency-dependent motions that produce noise under dynamic load inputs. Countervail was developed to reduce dynamic mobility at minimum weight added.

EXPERIENCE THE BENEFITS OF COUNTERVAIL TECHNOLOGY

IMPROVED PERFORMANCE, REGARDLESS OF THE SOURCE

There are numerous structure-borne noise sources that must be treated to ensure passenger comfort.

AN ENGINEERED SOLUTION

Through strategic material placement, Countervail can deliver damping values needed to treat offending vibration modes.

SOUNDS GOOD

Lower dynamic mobility means a more traditional-sounding vehicle while meeting weight reduction goals.

ENSURE COMPONENTS PERFORM AS DESIGNED

Need to manage dynamic load inputs into sensitive equipment mounted to lightweight panels?

Add Countervail and reduce road-induced vibration motions to increase mean time between failures.
