Abstract

FBG (Fiber Bragg Grating) sensor is suitable to detect track strain under harsh environment. In order to optimize its detecting efficiency, the key is to find out where the optimal detecting place is. This paper presents an FEA (Finite Element Analysis) method to analyze strain distribution of a track under load. The strain field is decomposed into three vector fields, and the optimal detecting place is determined by analyzing these vector fields. The related experiment and actual aplication verified the authenticity of this method.
