| dc.description.abstract | The purpose of this thesis is to study wear resistance of wheel-rail contact materials of Manganese steel and Pearlite steel. The wheel-rail contact is a critical interface in the railway technology and study of failures in most railways may cause due to wear of wheel-rail contact surfaces. Application of this thesis is on railway technology in the specific area of Addis Ababa Light Rail Transit. It is a new railway technology in Ethiopia. So researches on this area are needed to identify the existing problems and to avoid such problems from the start. The method of this thesis is numerical and analytical analysis of wear resistance of Manganese and Pearlite steels. Based on this method wear and wear resistance of wheel-rail contact materials are evaluated. Using the results of wear and wear resistance of Manganese Steel (current material of Addis Ababa Light Rail Transit) is compared with Pearlite Steel (new material). Since, wear volume of Manganese steel and Pearlite is 0.00169 m 3 3 and 0.00141m respectively at maximum load and maximum distance traveled and wear rate value of Manganese steel is 0.00000335 m 3 /m and Pearlite steel is 0.00000205m 3 /m. On the other hand wear resistance value of Manganese steel and Pearlite steel is 3.98e 5 5 3 and 4.88e m/m respectively. And also wear index value of Manganese steel is 1846.43 and 1599.97 for Pearlite steel. Results of this wear analysis shows that there is less amount of wear volume, wear rate and wear index in Pearlite steel than Manganese steel. On the other hand wear resistance of Pearlite steel has higher than Manganese steel. Finally, this thesis verified that Pearlite steel is better in hardness than Manganese steel. | en_US |
