A Study on the Characteristics of Elastomers for Vibration Isolation of Sports Utility Vehicle

Elastomers, which are engine mounts and body mounting rubbers, are traditionally designed for NVH use in vehicles, and they are designed to isolate specific unwanted frequencies. According to the measurement of the characteristics of engine mounts and body mounting rubbers, dynamic stiffness changes with respect to the driving miles accumulated in engine mounts and initial load in body mounting. This study looks at the variability in same engine mount properties, and the desired dynamic stiffness may increased with driving miles accumulated. And the dynamic stiffness of body mounting rubber changes very stiff above 150Hz.
