Abstract
The study rolling contact mechanics of wheel/rail-systems mainly involve the performance of wheel/rail mechanics in rolling contact.Based on the basic model of wheel/rail mechanics in rolling contact and principle of fiber-optical sensing technology
a fiber Bragg grating(FBG)sensing system without temperature effect was set up.Experimental results show that the FBG sensing system is durable and sensitive.It is believed that the technology have good forward.It can be an effective method for monitoring of track safety and track deformation.
