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 experiment modal analysis, hammer11 and medial axis it has possessed 13 and clutch 14.As for hammer 11, in order to detect bombardment generation timingIt has possessed power sensor 21. As for axis 13, hammer 11Base is supported revolution unrestrictedly. As for clutch 14, hammer11 is made to halt at the position where it is far from excitation position.
