Analysis of stick-slip effects to avoid disturbing interior noise
During vehicle dynamics, relative movements between two components can occur. The resulting transition from static to kinetic friction is known stick-slip effect the cause of creaking noises in the vehicle interior . These noises occur where, for example, parts made of plastic, leather, rubber, and glass come into contact and rub against each other.
Vehicle acousticians face the challenge of identifying contact points that promote the stick-slip effect early in the development phase.
AKE technologies offers a compact, portable stick-slip test bench that enables an objective evaluation of a wide variety of material pairings.
