US Patent 11781617 Driveshaft-damper tuning

Attenuation strips are provided for use in driveshaft dampers, and driveshaft dampers are provided for use in driveshafts to dampen or attenuate aspects of noise, vibration, and harshness (NVH). Systems and methods for making and using driveshaft dampers are further provided. The driveshaft dampers may be made using a helical-winding process and include attenuation strips with elongate protrusions. Various embodiments of helically-wound driveshaft dampers include a core and one or more attenuation strips helically wound around the core. The driveshaft dampers may be tuned to provide improved NVH reduction by reducing problematic NVH for a particular driveshaft as installed in a particular vehicle.
