• 557 Experimental Verification About the Dimensions os Smart Washer for the Bolt Looseness Detection

抄録

The objective was to apply a structural health monitoring concept to detect loosening of a bolt without human involvement. This paper proposes a new method of a bolt loosening detection by adopting a smart washer which uses a piezoelectric material. The proposed washer is a cantilevered plate type patched piezoelectric material. A self-sensing and actuation function featuring this material is applied to the washer. The natural frequency of the smart washer was identified with sub-space state space identification method. There was good correlation between the change of the natural frequency of the smart washer system and the decrement of bolt tightening axial tension. A result of an experiment was shown about the influence which the dimension of the smart washer and operation exert on the detection precision. A subject for the realization of loosening detection by using smart washer was mentioned.
