Method on Whole Rail Profile Auto-Matching and its Application in Urban Rail Transit

Abstract:

With the increase in rail inspection technology, the whole rail profile can be measured by rail inspection cars or some typical static measurement instruments. Based on a large number of practical rail profile measurements, a whole rail profile auto-matching method is put forward to enhance the efficiency and accuracy of data analysis. An analytical tool applying this method is developed at the same time and the principle and calculation method of the tool will be introduced. Apart from this, data collected from in-situ measurements taken on line 2 of the Shanghai Metro will be performed and analyzed to verify this method. The main contributions of this paper are the generalization of an efficient analytical tool for the calculation of wear parameters at both specific and non-specific points and the practical application for comparison of data collected by both dynamic and static inspection with the standard, which proves that the method is correct and effective.
