TEST METHOD AND APPARATUS FOR ASSESSING A TENDENCY TO SQUEAK

摘要

The invention relates to a test method and apparatus for assessing whether a n assembly, which comprises as components at least a gasket (1) and a substrat e (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 t o the substrate, in particular by means of an oscillator (15). In contrast to the existing methods which are based on acoustic measurements, the test meth od according to the invention is not influenced by background noises so that no acoustic insulation is required.
