摘要
The types of exciters were investigated experimentally. One of the exciters uses a small permanent magnet fastened on the object. The force is introduced by the change in the electromagnetic field from a coil via an air gap. The second exciter is an eddy-current electromagnet one. The amplitude of the forces from these exciters are calibrated by using dynamic reciprocity in conjuction with electronic holography. These forces strongly depend upon the distance between the exciter and the object. (C) 1996 John Wiley & Sons, Inc.
