Abstract
The invention relates to a device for ascertaining mechanical properties, for example, the natural frequency, the damping or the natural vibration mode of a test specimen containing ferromagnetic material components, in particular a brake pad for a motor vehicle. An electromagnetic actuator, in particular an electromagnet, is provided for exerting a magnetic attractive force onto the test specimen so that the actuator exerts a force impulse that imparts the test specimen with vibrations whose spectrum of vibration contains at least one natural frequency vibration of the test specimen.
