Finite Element Analysis of Rail Wheel Interaction

Abstract

The rail wheel interaction is one of the important mechanics for the study in Railway Engineering, requiring both vast application expertise and dependable analysis approaches. The contact area and pressure distribution in a wheel/rail contact is essential information required in any fatigue or wear calculation and to determine design life, regrinding and maintenance scheme. The objective of this project is to understand, formulate and simulate wheel-rail interaction analysis at static conditions with a view to optimize the wheel and to optimize the mass of the railway wheel subjected to both vehicle load and contact pressures. In railway, engineers applied one of the numerical computation techniques known as Finite Element Analysis (FEA) into Rail-Wheel contact problems to validate their results by comparing them to their real life data obtained over the years. So we have used software ANSYS in this research for Finite analysis of rail wheel interaction

Thermal model for bicycle tire internal temperature evaluation in various contact conditions

“…The design and materials used in bicycle tires have been subjects of dedicated research in recent years, with the overarching goal of enhancing their efficiency and safety. Much of this research has encompassed empirical correlation activities [17] and Finite Element Analysis (FEA) models [13]. While these endeavors have yielded valuable insights, there remains a notable gap in the availability of comprehensive multiphysics mathematical models capable of analyzing and replicating the intricate tire-road contact phenomena [16].…”

Thermal model for bicycle tire internal temperature evaluation in various contact conditions

“…The importance of bike tire optimization cannot be underestimated as it can affect both the bicycle dynamics and bicycle performance. In recent years, research has focused on improving the design and materials used in bike tires to enhance their efficiency and safety, mainly investing on empirical correlation activities (Steyn, 2014) and FEA models (Kumar, 2018). Due to the lack of multi-physical mathematical models able to analyze and reproduce complex tire/road contact phenomena, useful to predict the wide range of working conditions, this research aims to the development of a bicycle tire thermal model.…”
