چکیده مقاله :
Higher-performance tapered roller bearings are required to increase freight vehicle loads. More development is needed for the modeling tools and techniques utilized for subsurface contact stress evaluations, as the stress condition on railway bearing applications is rising. Railway-bearing contact geometries and heat treatment standards were first created under ideal load circumstances. Nonetheless, tapered roller bearings are subjected to various load conditions which are rarely ideal in railroad applications. Furthermore, there are frequent variations in bearing loads, railcar wear conditions, maintenance procedures, and reliability vs utilization expectations when comparing global rail markets. In the current research paper, the bearing with different special shapes is modeled using the finite element method under loading conditions. Also, the obtained results are compared to those obtained theoretically. The results reveal that the finite element modeling can predict the theoretical observations and finally, it can be concluded that the shapes of the bearings influence the stress distributions in the systems.
