With dynamic driving excitation, relative movements of two components can occur. The resulting transition from static to sliding friction is called a stick-slip effect. This is considered as the cause of the generation of creaking noise in the vehicle interior. These noises occur in places where, for example, parts of plastic, leather, rubber and glass come into contact with and rub against each other.

Vehicle acousticians are faced with the challenge of early detection of contact points in the development phase, which can cause the stick-slip effect. AKE-technologies offers a compact, portable stick-slip test bench that enables an objective evaluation of a wide range of material pairings. The test results meet the standards of the globally recognized VDA 230-206 or various car manufacturers.
