3072. Investigation Of Wheel Wear Behaviors Subjected Under Dry And Wet Loading Conditions A Case Study Of Addis Ababa Light Rail Transit
Wheel/rail wear continues to be an important factor that limits the service life of rolling stock. Wheel-rail surfaces are subjected to contact stresses that results in surface damage which is observed as either wear or contact fatigue damage mechanisms. The contact stresses are the result of train...
3073. Numerical Analysis Of Wear Behavior Of Rail Material A Case Study On Addis Ababa Light Rail Transit
The railway track is one of the most important element of a railway system. During passage of trains, the rails are subjected to contact load that comes from the wheels of the train. The railway track often fail in service due to wear caused by contact fatigue and other wear damage mechanisms. It...
3074. Experimental Investigation Of The Engineering Properties Of Railway Bituminous Blanket Modified With Waste Steel Slag
Increasing the axle load and speed on existing railway lines is one of the railway industry’s approach that has been taken to improve the rail transport system. In this regard, improvement in stability of railway embankments, in terms of blanket layer inclusion, as an important part of each...
3075. Investigation On The Effect Of The Internet Of Things (iot) Technology To Improve Traction Safety.
Electric trains are made up of various safety-sensitive systems, these systems are safety-sensitive in that a simple loophole can compromise the train’s safety and may lead to catastrophic incidents and accidents. These systems are usually maintained regularly at set schedules and...
3076. Influence Of Non-uniform Railway Track Modulus On Wheel-rail Contact Dynamic Forces And Wheel Tread Wear
The current trend of increased speeds and axle loads in the railway industry has led to accelerated wear of railway contact materials. This effect has brought with it new technological challenges including the monitoring and optimization of the wheel-rail interface parameters. For predictive...
