In the low frequency range, mechanical vibrations propagate into the car body by structure borne transmission. In order to limit this transmission, an original system called “Vibration Barrier” has been developed. It reduces the vibrations propagating into the hollow body network (the transmission path) using a cavity part and the high damping foam technology.
This paper describes the general concept and the FEA design process of a Vibration Barrier part. An example is given for a full car body. The best compromise of the tested designs leads to a significant reduction of the structure borne noise using a lightweight part.
