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 axis it has possessed 13 and spring 12. HammerAs for 11, the power sensor in order to detect bombardment generation timingIt has possessed 21. As for axis 13, base of hammer 11 timeRevolution it supports unrestrictedly. As for spring 12, in free state hanWay ma 11 it lays out in the position where it is far from excitation position, hanma it concatenates with 11 and axis 13 elastically.
