    摘要: An apparatus and associated method is provided for suspending a test object in a gravitational field from a support member, exciting the test object by noncontactingly engaging it with a predetermined waveform force, and characterizing the test object qualitatively in relation to an observed modal frequency response of the test object to the excitation.
