Abstract
Rail flatness is an essential indicator of large rail components’ quality, and is of great significance in inspecting the product quality of rail mills. The high-speed railways can only be built by rails with excellent flatness, while the standard ones are built by those with moderate defects in this respect. However, the rails must be straightened or discarded once the flatness are out of specific tolerances. In order to measure flatness, a gravitational straightedge method of adaptive two-end growth is proposed. This paper extracted the original flatness curve with a laser profilometer and calculated the maximum difference using the processing method for such curve. According to comparison of experimental data, the precision in repeatability was ±0.01 mm in such measurement conducted based on this algorithm, showing a difference of less than 0.02 mm compared with that achieved manually with a mechanical straightedge. Therefore, the algorithm was proved to be highly robust and accurate.
