Sometimes, the best solution is a quieter one, a smoother one.
Vibracoustic S.E., a global manufacturer of noise, vibration and harshness products, is developing those kinds of solutions with its rubber-based decoupling products that are designed to help auto makers manage emerging noise and vibration challenges. The newest NVH challenges come from auxiliary systems—such as coolers, pumps and compressors—that are no longer belt-driven in e-mobility applications.
Vibracoustic's decoupling solutions—made primarily of rubber—consider vehicle NVH needs and include the option for single- or double-isolation layers, according to Hans Windahl, vice president of Vibracoustic's global application team for isolators and dampers. A double-isolated bracket was used for a vacuum pump for the braking system of a standard C-segment vehicle to eliminate unwanted noises of the braking system. While these NVH issues had no impact on the performance of the vehicle's braking system, many customers would perceive this as a critical safety issue or attribute it to poor quality.
