VIBRATION TESTING DEVICE, VIBRATION TESTING METHOD, AND VIBRATION TESTING JIG FOR STRUCTURE

摘要

PURPOSE: To combine the vibration response calculation of a primary structure and the vibration test of the secondary structure together so as to accomplish an economical and highly precise vibration test. ;CONSTITUTION: On the basis of a vibration response calculation of a primary structure, an excitation signal for a vibrating table test of a secondary structure 4 is prepared, and a load from the secondary structure 4 is used for a vibration response calculation. For measuring the load, the secondary structure 4 is placed on a vibration testing jig, which is movable in the excitation direction. The vibration testing jig consists of a supporting member 14, which is movable in the excitation direction, a base plate 15, and the like.;COPYRIGHT: (C)1995,JPO
