A Study on FBG Vehicle Loading Sensing System

Abstract:

This study considered the application of fiber Bragg grating (FBG) to a composite material leaf spring as a vehicle loading sensing system. The loading of the vehicle by the leaf spring was calculated by the period change of the fiber grating caused by deformation of the composite material leaf spring under loading. From the experiment results, a good linear relationship between loading and Bragg wavelength shift for light. The R-squared value for the linear regression reached 0.99. The loading sensitivity is about 0.267 nm/N.
