Research on Inspection Method for Large Radius Curve Parameters of High Speed Railway

For high speed railway to meintain the good state of curves is important to improve passenger comfort and ensure running safety.It is the premise of the maintenance work of high speed railway to realize curve discrimination and curve element inspection by using track inspection vehicle.An algorithm model for parameter inspection of large radius curve of high speed railway was proposed in this paper.The key parameters affecting curve detection were found out.The appropriate threshold of key parameters was given which was verified by field tests.Finally a set of methods for large radius curve inspection of high speed railway was obtained.
