Analysis of wheel and rail Hertzian and Non-Hertzian contact theories using UM software considering the effect of rail inclination on wheel wear
Wheel-rail interaction has always been one of the issues in the railway industry. In this paper, the effect of Hertzian and non-Hertzian contact theories on the wheel wear due to the rail inclination was investigated. by using the UM software. According to the results, longer contact areas are obtained in non- Hertzian contact theory compared to Hertzian contact theory. In non-Hertzian contact...
متن کاملDetermining a Surrogate Contact Pair in a Hertzian Contact Problem.
Laboratory testing of contact phenomena can be prohibitively expensive if the interacting bodies are geometrically complicated. This work demonstrates means to mitigate such problems by exploiting the established observation that two geometrically dissimilar contact pairs may exhibit the same contact mechanics. Specific formulas are derived that allow a complicated Hertzian contact pair to be r...
متن کاملThe Investigation of the Effect of Contact Frequency upon Thermal Contact Conductance
Thermal Contact Conductance (TCC) between an exhaust valve and its seat is one of the important parameters to be estimated in an internal combustion engine. An experimental study presented here to acquire temperature in some interior points to be used as inputs to an inverse analysis. An actual exhaust valve and its seat are utilized in a designed and constructed setup. Conjugate Gradient Metho...
