| Abstract: | Based on the requirements of temperature measurement calibration of high speed dynamic temperaturemeasurement system for ballastless track slab,a portable temperature measurement target for ballastless track slab wasdeveloped to simulate the temperature radiation characteristics of track slab.This paper introduced the developmentscheme of the temperature measurement target of ballastless track slab,including its body,heating and cooling,temperature control and anti-frosting key module,and designed the test of temperature measurement target forballastless track slab.The test results show that the temperature measurement target of ballastless track slab can realizethe temperature control from-40℃to 60℃,the error is less than 0.5℃,and the temperature stability is good.It can beused for the calibration of high speed dynamic temperature measurement system for ballastless track slab. |
