Abstract
The present paper focuses on study of parameters such as lateral force, wagon weight, rail path curvature, train speed and path slop those have greatest effects on wear mechanism of wheel and rail. ADAMS-RAIL simulation software was used for dynamical modeling of train while moving via railway. Some experimental tests were carried out to evaluate the wear loss obtained from these parameters. Results indicated that in railway with high path curvature higher lateral force affects on wheelsets. Moreover, high train speed resulting lower derailing probability. Furthermore, cant has a significant effect on critical rates like derailing. And also, it is influential on wheel and rail lateral force and decreases the wear between rail and wheel. By increasing in lateral force from 46N to 64N, the wear rate increases about 66% and by increase in slip velocity the wear rate also increases.
Highlights
Wear phenomenon extensively affects in life of parts those are used in industry and damages their safety
Wear phenomenon between rail and wheel is a complex type of wear phenomena in which many parameters are contributed
High amount of published papers in this area implies the importance of wear behavior in railway industry
Summary
Wear phenomenon extensively affects in life of parts those are used in industry and damages their safety. It is one of major challenges in the case of rail transportation industry. Subway transpirations systems suffer higher values of wear due to their due to higher path curvature while compared with suburban transportations [1, 2]. Designing of optimal wheel profile based on wear behavior [3], numerical index as comparison tool [4] and estimation of wheels and rails life through simulation [3] are types of the works in the case of wear analyzing of railway industries [5]
