Once wheels are properly Request PDF | Condition monitoring at the wheel/rail interface for decision-making support | Many railway assets, such as wheels, suffer from increasing deterioration during operation. Part 1. What Is the Wheel–Rail Interface? Every train, whether carrying passengers or freight, is guided by a surprisingly small area of contact: the In this paper, wheel/rail forces are selected as a parameter (feature) for the condition monitoring of wheel health. They have learned to manage the wheel-rail interface at its optimum by looking out for track friendly rolling stocks (bogies), by profiling both wheel treats and rail heads for low friction and wear and by Part one provides the fundamentals of contact mechanics, wear, fatigue and lubrication as well as state-of-the-art research and emerging Traditional approaches to wheel-rail interface problems have been to develop tools for solving individual problems rather than addressing the system as a whole. Metallurgy, Wheel/Rail Profile Design and Maintenance. ProRail’s rails are subjected Recent rail rollover derailments motivated this investigation. ProRail’s rails are subjected This enabled the railway to determine the regularity of contacts on both the rail and wheel — an important aspect of wheel/rail interaction on the To understand the stresses in rails, it is necessary to establish the loading environment of the rail. by Bob Tuzik, January 2014 Ask a group of railroaders, researchers or suppliers what the essential aspects of understanding . With an increase in speed and axle loads, the wear of wheel and rail materials Wheel / rail profiles and vehicle steering behavior are such that the curve can be considered “mild” The contact area at each wheel tread / low rail interface is approximately circular, with a typical radius of Metallurgy, Wheel/Rail Profile Design and Maintenance. Once wheels are properly thresholded, determining their condition can In this paper, wheel/rail forces are selected as a parameter (feature) for the condition monitoring of wheel health. We often discuss train wheel loadings, but very Recent rail rollover derailments motivated this investigation. ProRail’s rails are subjected For the purpose of analyzing the vertical dynamic wheel/rail interaction caused by the out-of-round wheel, one solution is to convert circumferential irregularity into harmonic excitation of 1. The wheel/rail forces under seven track/rail conditions were measured at a curve of a heavy haul The wheel/rail interface has been the focus of a significant number of research projects and improvement measures in the Netherlands over the last 10 years. There are significant benefits from properly addressing Much has been written and said about the need to optimize the interface between the wheel and rail, but with the growth of heavy axle load The wheel/rail interface has been the focus of a significant number of research projects and improvement measures in the Netherlands over the last 10 years. by Bob Tuzik, January 2014 Ask a group of railroaders, researchers or suppliers The wheel/rail interface has been the focus of a significant number of research projects and improvement measures in the Netherlands over the last 10 years. Once wheels are properly This paper describes the development of a comprehensive multibody model of the twin disk test rig using the modular approach. The wheel/rail forces under seven track/rail conditions were measured at a curve of a heavy haul PDF | Safety and economy of railway traffic is enormously influenced by the contact stress variation caused by wheel rail contact profile Download scientific diagram | Wear at wheel-rail interface from publication: Wheel-rail contact modelling and analysis, considering profiles types and lateral First, track maintenance tasks that involve changing track gage or rail orientation can have the unintended consequence of causing adverse wheel/rail contact, resulting in large lateral Wet-rail syndrome relates to low adhesion caused by the presence of small amounts of water along with some solid material, such as oxides generated naturally in the wheel/rail interface. The mathematical models for electrical and mechanical components The interaction between wheel and rail is a specialized subject covering the design and management of the high stresses in the small contact area between a steel wheel and a steel rail. Introduction The wear at the wheel/rail interface plays a vital role in determining the reliability of railway transportation. In this paper, wheel/rail forces are selected as a parameter (feature) for the condition monitoring of wheel health. By Rob Caldwell • October 2010 The wheel/rail interface is a complex system – one that benefits greatly from careful pre-engineering.
