Abstract

Fiber Bragg Grating(FBG) sensor with a stickup plane structure can not test the strain precisely in ship structure health monitoring due to its small measuring range. For overcoming this problem

this paper designs a composite structure stickup FBG sensor composed of an annular plane spring and a slab on the basis of stainless steel. This kind of stickup FBG sensor can convert the large strain of composite structure into a small strain of FBG by the annular plane spring. By decreasing the strain coupling coefficient between FBG and tested structure

large-scale strain test is implemented. The sensing principle of the composite structure is analyzed and the stress and strain distribution of the stickup FBG sensor are simulated through finite element method. The simulation result demonstrates the feasibility of this structure in a large strain test. Finally

a loading experiment are performed on a special steel sample. The experiment result shows that this structure has a measuring range more than 20 000 με and good linearity. In addition

the correlation coefficient is up to 0.99. As a conclusion

the sensor is convenient for setting up because of the small volume

and can resolve the problem of large strain test in ship structure health monitoring with good performance.
