| Abstract: | Optical fiber sensors have received increasing attention in the fields of aeronautic and civil engineering for their su-perior ability to stand explosion,immunity to electromagnetic interference and high accuracy,especially fit for measure-ment applications in harsh environment.In this study,a novel FBG(fiber Bragg grating)strain sensor,which is pack-aged in a1.2mm stainless steel tube with epoxy resin,is developed.Experiments are conducted on the universal materi-al testing machine to calibrate its strain transferring characteristics.The sensor has the advantages of small size,high pre-cision and flexible use,and exhibits promising potentials.Five tube-packaged strain FBG sensors have been applied to the vibration experiment of a submarine pipeline model.The strain measured with the FBG sensor agrees well with that measured with the electric resistance strain sensor. |
