When two materials, excited by vibrations, do not move to the same degree, but pass over in cyclical sticking and slipping, this is referred to as the 'Stick-Slip' effect. This is regarded as the main cause of disruptive noise generation in the vehicle interior. The successful reduction of outside noises results in the noises generated in the interior by acoustically inferior paneling being perceived more markedly. Disruptive noises generated by the Stick-Slip effect predominantly occur at places where parts made of plastic, leather, rubber and glass come into contact and rub against each other.
Vehicle acoustic engineers are faced with the challenge of tracking down points of contact which foster the Stick-Slip effect at any early stage in the development phase. AKE-technologies provides a compact, mobile Stick-Slip test stand for this, which allows an objective evaluation of a very wide range of material pairings. Here, the traveling speed and down-force can be variably adjusted. The test results fulfill the standards of VDA 230-206 or various automobile producers.
