Railway risk assessment - the fuzzy reasoning approach and fuzzy analytic hierarchy process approaches: A case study of shunting at Waterloo depot
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit - Tập 221 Số 3 - Trang 365-383 - 2007
Min An, Shifeng Huang, Chris Baker
Railway safety is a very complicated subject, which is determined by numerous aspects including human error. Many of the railway risk assessment techniques currently used are comparatively mature tools. However, in many circumstances, the application of these tools may not give satisfactory results because the risk data are incomplete or there is a high level of uncertainty involved in th...... hiện toàn bộ
Development of a design for a crash energy management system for use in a railway passenger car
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit - Tập 230 Số 1 - Trang 206-219 - 2016
Ahmad Partovi Meran, Cengiz Baykasoğlu, Ata Muğan, Tuncer Toprak
A design approach for a crash energy management (CEM) system for a N13-type railway passenger car used by the Turkish State Railway Company is developed in this paper. The components of the CEM system are honeycomb-structured boxes, primary energy absorbers, shear bolts, a sliding sill mechanism and a fixed sill mechanism that are located in the passenger-free space at the end of the pass...... hiện toàn bộ
Out-of-round railway wheels—wheel-rail contact forces and track response derived from field tests and numerical simulations
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit - Tập 217 Số 2 - Trang 135-146 - 2003
Anders Johansson, Jens C. O. Nielsen
The influence of different types of railway wheel out-of-roundness (OOR) on the vertical dynamic wheel-rail contact force and track response is investigated through extensive field tests and numerical simulations. The response from a freight train, provided with a number of different types of severe wheel tread damage, is studied. Two different axle loads are used in combination with diff...... hiện toàn bộ
Machine Vision Condition Monitoring of Heavy-Axle Load Railcar Structural Underframe Components
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit - Tập 224 Số 5 - Trang 499-511 - 2010
Bryan W. Schlake, Sinisa Todorovic, J. Riley Edwards, John M. Hart, Narendra Ahuja, C P L Barkan
To ensure the safe and efficient operation of the approximately 1.6 million freight cars (wagons) in the North American railroad network, the United States Department of Transportation (USDOT), Federal Railroad Administration (FRA) requires periodic inspection of railcars to detect structural damage and defects. Railcar structural underframe components, including the centre sill, sidesill...... hiện toàn bộ
Optimisation of schedules for the inspection of railway tracks
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit - Tập 232 Số 6 - Trang 1577-1587 - 2018
Mohd Haniff Bin Osman, Sakdirat Kaewunruen, Anson Jack
Inspection of railway tracks involves a high volume of short-duration tasks (e.g. visual inspection, vehicle-based inspection, measurement, etc.) each of which is repeated at different frequencies and time intervals. It is important to gain as many benefits as possible from the inspection tasks, which incur huge expenses. To date, various optimisation methods have been incorporated into t...... hiện toàn bộ
Mitigating train-type heterogeneity on a single-track line
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit - Tập 227 Số 2 - Trang 140-147 - 2013
Mark H. Dingler, Yung-Cheng Lai, Christopher P. L. Barkan
North American railroads are experiencing growth in traffic demand and increasingly need to expand capacity on their lines; this will require changes in the mode of operation and infrastructure. Infrastructure expansion requires long lead times and is capital-intensive. Alternatively, some additional capacity may be achieved by alteration of the mode of operation which is often less expen...... hiện toàn bộ
Analyzing the transition from single- to double-track railway lines with nonlinear regression analysis
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit - Tập 230 Số 8 - Trang 1877-1889 - 2016
Samuel L. Sogin, Yung-Cheng Lai, C. Tyler Dick, Christopher PL Barkan
The demand for freight rail transportation in North America is anticipated to substantially increase in the foreseeable future. Additionally, government agencies seek to increase the speed and frequency of passenger trains operating on certain freight lines, further adding to demand for new railway capacity. The majority of the North American mainline railway network is single track with ...... hiện toàn bộ
A study of railway wheel profile parameters used as indicators of an increased risk of wheel defects
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit - Tập 230 Số 2 - Trang 323-334 - 2016
Matthias Asplund, Mikael Palo, Stephen Mayowa Famurewa, Matti Rantatalo
The capacity demands on railways will increase in the future, as will demands for a robust and available system. The availability of a railway system is dependent on the condition of its infrastructure and rolling stock. To inspect rolling stock so as to prevent damage to the track due to faulty wheels, infrastructure managers normally install wayside monitoring systems along the track. S...... hiện toàn bộ
Condition monitoring approaches for the detection of railway wheel defects
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit - Tập 231 Số 8 - Trang 961-981 - 2017
Alireza Alemi, Francesco Corman, Gabriël Lodewijks
Condition monitoring systems are commonly exploited to assess the health status of equipment. A fundamental part of any condition monitoring system is data acquisition. Meaningfully estimating the current condition and predicting the future behaviour of the equipment strongly depend on the characteristic of the data measurement stage. Nowadays, condition monitoring has wide applications i...... hiện toàn bộ
Evaluation of dynamic and impact wheel load factors and their application in design processes
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit - Tập 231 Số 1 - Trang 33-43 - 2017
Brandon J. Van Dyk, J. Riley Edwards, Marcus S. Dersch, Conrad Ruppert, Christopher P. L. Barkan
A sustained increase in heavy axle loads and cumulative freight tonnages, coupled with increased development of high-speed passenger rail, is placing an increasing demand on railway infrastructures. Some of the most-critical areas of the infrastructure in need of further research are track components used in high-speed passenger, heavy haul and shared infrastructure applications. In North...... hiện toàn bộ
