Supporting Apparatus for Vibration Test using Air Spring

摘要

PURPOSE: A supporting device for a vibration test using an air spring is provided to support a test object structure with the pressure of compressed air by attaching an air tank of a large volume to an air spring and to utilize a spherical bearing in order not to detain a horizontal directional motion, thereby obtaining a free supporting state of the air spring.;CONSTITUTION: A supporting device for a vibration test comprises a supporting structure(10), an air spring(20), a supporting stand(30), and an air tank(40). The supporting structure is installed on a floor. The air spring is joined to the upper part of the supporting structure. The air spring comprises a bellows(21), a bracket(22), and an air duct connector(23). The supporting stand is attached on the top of the air spring, thereby transferring a load of a test object structure to the air spring. One side of the air tank is connected to the air spring by an air supplying pipe(41) and the air tank is filled with compressive air flowing from outside through an air inlet(42) arranged in the other side of the air tank.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Compressed air
