Abstract

Dynamic response of lightweight structures is affected by the mass of a transducer. The additional mass of the transducer is defined as a mass loading for the system, which is comparable to the weight of the structures, such as composites and thin cantilever beam/bar. In this paper, we measure the bending and torsion mode frequencies with and without mass loading to the lightweight structures by using lightweight optical fiber sensor (OFS) and conventional accelerometer. The frequency difference is verified by the finite element method using ANSYS software. The OFS, benefited to its lightweight, has shown the advantage of measuring vibration frequency accurately without affecting the dynamic response of the structure.
