Abstract
Maintaining or improving acoustic and vibration quality of vehicles, the automotive industry continually faces design goals to reduce weight and manufacturing cost. In light of these objectives, advanced material design techniques facilitate the development of a high performance bulk applied constrained layer vibration damper aimed at improved automotive acoustics.
The overall vehicle acoustic and vibration quality relies heavily on floor pan vibration dampers. A review of current industry damping technologies is addressed. Industry migration to bulk applied extensional dampers from the once ubiquitous asphalt sheet damper is discussed. Furthermore, this paper addresses the development of a new bulk applied constrained layer damper technology that delivers superior acoustical performance. The paper presents the chemistry formulation, the prediction of analytical results, and experimental validation.
