DEVICE AND METHOD FOR VIBRATION TEST

摘要

PROBLEM TO BE SOLVED: To make a distributed displacement able to be loaded in a specimen during the course of a hybrid test during which excitation tests are performed by means of exciters, by loading a part of a structure in a computer by numerically modeling the part and using the other part of the structure as an actual model. SOLUTION: A hybrid vibration testing device for structure excites an actual model 6 imitating the part of the structure and, at the same time, analyzes the vibration response of a numerical model imitating the rest of the structure by using the computer 10. A loading member 2 is provided adjacently to the actual model 6 and a plurality of exciters 1a-1c excites the actual model 6 through the loading member 2. A control means 40 for the exciters 1a-1c controls the exciters 1a-1c so that the distribution displacement may be loaded in the actual model 6. COPYRIGHT: (C)2003,JPO
