Abstract |
In order to measure the deformation of the rail according to the operation of the railway vehicle, a strain gauge measurement method under various conditions was used. As a result of measuring strain at the upper, middle and lower positions of the rail, the optimal position of the strain gauge was the lower part of the rail side. The part where the deformation of the rail occurred the most was the upper part of the side. But considering the durability and installation safety of the strain gauge, the lower part where the second largest deformation occurred was considered to be the most suitable. As a result of measuring rail deformation by installing strain gauges at short and long distances, almost all rail deformations were reduced before and after wheel tread maintenance compared to maintenance. |
