oa Civil Engineering = Siviele Ingenieurswese - Track deflection measurement using particle image velocimetry
A new optical track deflection measurement device was developed for Transnet Freight Rail (Track Technology) to be used for track research carried out in both field and laboratory investigations. The functioning and calibration of the system are demonstrated and examples are given of measurements taken on the South African rail network. The article discusses the advantages of the system, further developments and the implications for design and analysis.
