APPARATUS FOR TESTING DYNAMIC VIBRATION DAMPING TYPE ACTIVE VIBRATION-PROOF APPARATUS

摘要

PURPOSE: An apparatus for testing a dynamic vibration damping type active vibration-proof device is provided to determine the attenuated degree of vibration which is caused by a vibrating means, through the position change of a vibrating beam in accordance with the vibration. CONSTITUTION: An apparatus for testing a dynamic vibration damping type active vibration-proof device(100) includes a vibrating beam(300), an elastic supporting means(310), and an excitation means(200). The active vibration-proof device is mounted at one side of the vibrating beam. The elastic supporting means elastically supports the reference position of the vibrating beam. The excitation means generates a wave exciting force having uniform size. The wave exciting force is transferred to the active vibration-proof device through the vibrating beam.
