Abstract
An exciter device is configured to apply both a vibrational force and an impact force to a device-under-test. A first end of a piston is couplable to the device-under-test and a second end of the piston is aligned with a position of an impact hammer tip. The impact hammer tip and an electromagnet are both coupled to a moveable housing that is positioned around the piston. The exciter device applies a vibrational force to the device-under-test when an alternating magnetic field is applied by the electromagnet to the permanent magnet causing a linear reciprocating movement of the moveable housing relative to the piston. The exciter device applies an impact force to the device-under-test when a magnet field is applied by the electromagnet to the permanent magnet causing a linear movement of the moveable housing that is sufficient to cause the impact hammer to contact the second end of the piston.
