DEFECT ANALYSIS ON LATVIAN RAILWAY, RESEARCH ON DEFECTIVE RAIL

The article is focused on the study of the defective rails on the Latvian railway. The analysis of defects on the Latvian railway by eight sections of the division during 2013, 2014, and 2015 has been performed in the paper. Statistical data about defective rails have been collected and processed. The main classification of defects was considered, the interpretation of each type of defect was analyzed separately. The graphs analyzing quantitative classification of defective rails in each division were built. The aim of this paper is the study of the isolated defective rail. The study process consisted of three stages. The first stage is a determination of hardness of the metal on the Brinell scale with a modern instrument "Krautkramer". The analysis of the results obtained should be performed and compared with the data of the manufacturer. The second stage is a determination of the chemical composition of rail steel with the "ARC-MET 8000 Mobile Lab" optical-emission analyzer. The data obtained should be compared with the data of the manufacturer as well as with the standard data. The main conclusions of the work that was done should be performed in the third stage of the study.
