The objective was to apply a structural health monitoring concept to detect loosening of a bolt without human involvement. The smart washer has with a part of the cantilever is able to detect the bolt loosening by using flexibility of cantilever and self-sensing/actuation function. The precision in case of the bolt loosening detection is necessary to confirm the influence of the temperture variation in the environment. Experimental results were shown about the influences of frequency characteristic depending on the temperature changing in this paper. This paper proposes a design method of the smart washer by using ANSYS, due to the smart washer is not yet enough to detect high sensitively the loosening.
