Track elastic strip vibration measurement

Case background

The change of surface displacement field and strain field in the course of track elastic strip vibration is studied to prevent the elastic strip from breaking and ensure the safety of railway traffic.

Inspection scheme

The measurement area is 200 mm X 150 mm. The high-speed camera (3M, 5 000 frames) is used to observe the displacement field and strain field of the elastic strip in the process of deformation. The two high-speed cameras collect data synchronously by simulating the train's vibration load.

Measurement process

The surface of the turbine is treated, the imaging agent is sprayed, the marking points are pasted and placed on the worktable. XTOM is used for scanning and data splicing automatically. Comparing the scanned data with the design model in Geomagic Qualify software and setting the corresponding tolerance, the corresponding test results can be obtained and the test report can be output.

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

The displacement field and strain field are analyzed, and the mechanical properties of the elastic strip are studied to ensure the safety of its installation and use.
