Rail track vibration deformation measurement

case background

Measuring coordinates and displacements of key points on the surface of rails during vibration

实验现场

Inspection process

（1）Paste marking points on the side of rails;

（2）Setting up camera position and calibrating camera internal and external parameters;

（3）The camera collects data synchronously when the rail is loaded artificially;

（4）Data analysis.

Data analysis

（1）Up and down knocking: Applying downward load to the rail, the displacement and deformation in the upper and lower directions

are obvious, and the maximum peak value is about 0.6 mm. After applying the load, the vibration gradually attenuates until the

final vibration stops.

（2）Front and back knocking: Applying front and rear loads to the rails, the displacement and deformation in the upper and lower

directions are obvious, and the maximum peak value is about 0.1mm. After applying the loads, the vibration gradually attenuates

until the final stop.
