TEST METHOD AND APPARATUS FOR ASSESSING A TENDENCY TO SQUEAK.

摘要

The invention relates to a test method and apparatus for assessing whether an assembly, which comprises as components at least a gasket (1) and a substrate (2) against which the gasket is pressed, has a tendency to squeak when the gasket (1) is moved relative to the substrate (2). For assessing said tendency, use is made of at least one accelerometer to detect whether vibrations are generated in the assembly when the gasket is moved relative to the substrate, in particular by means of an oscillator (15). In contrast to the existing methods which are based on acoustic measurements, the test method according to the invention is not influenced by background noises so that no acoustic insulation is required.
