Excitation device for experiment modal analysis

摘要

(57) Abstract Objective As the exciting force which it stabilizes is obtained, two degree hittingIt prevents. Constitution As for excitation device 1 for experimental modal diffraction, revolving shaft 13 and hammer 11 and one-way clutch 14 and suIt has possessed with totsupa 16. As for hammer 11, bombardment generationIt has possessed the power sensor 21 in order to detect timing,ru. As for one-way clutch 14, only one time revolution direction relative timeWay revolution is allowed, in revolving shaft 13 the base of hammer 11It concatenates. Stopper 16 turns with bombardment generation timingRevolution of axis 13 is made to halt.
