| 1 | Longitudinal dynamics and energy analysis for heavy haul trains显示文摘Whole trip longitudinal dynamics and energy analysis of heavy haul trains are required by operators and manufacturers to enable optimisation of train controls and rolling stock components. A new technology named train dynamics and energy analyser/train simulator(TDEAS)has been developed by the State Key Laboratory of Traction Power in China to perform detailed whole trip longitudinal train dynamics and energy analyses. Facilitated by a controller user interface and a graphic user interface, the TDEAS can also be used as a train driving simulator. This paper elaborates the modelling of three primary parts in the TDEAS, namely wagon connection systems, air brake systems and train energy components. TDEAS uses advanced wedge-spring draft gear models that can simulate a wider spectrum of friction draft gear behaviour. An effective and efficient air brake model that can simulate air brake systems in various train configurations has been integrated. In addition, TDEAS simulates the train energy on the basis of a detailed longitudinal train dynamics simulation, which enables a further perspective of the train energy composition and the overall energy consumption.To demonstrate the validity of the TDEAS, a case study was carried out on a 120-km-long Chinese railway. The results show that the employment of electric locomotives with regenerative braking could bring considerable energy benefits. Nearly 40 % of the locomotive energy usage could be collected from the dynamic brake system. Most of tractive energy was dissipated by propulsion resistance that accounted for 42.48 % of the total energy. Only a small amount of tractive energy was dissipated by curving resistance, air brake and draft gear systems. | Qing Wu Shihui Luo Colin Cole | 2014 | Journal of Modern Transportation2014，22，3： | 7 |
| 2 | A review of hydrogen technologies and engineering solutions for railway vehicle design and operations显示文摘Interest in hydrogen-powered rail vehicles has gradually increased worldwide over recent decades due to the global pressure on reduction in greenhouse gas emissions,technology availability,and multiple options of power supply.In the past,research and development have been primarily focusing on light rail and regional trains,but the interest in hydrogen-powered freight and heavy haul trains is also growing.The review shows that some technical feasibility has been demonstrated from the research and experiments on proof-of-concept designs.Several rail vehicles powered by hydrogen either are currently operating or are the subject of experimental programmes.The paper identifies that fuel cell technology is well developed and has obvious application in providing electrical traction power,while hydrogen combustion in traditional IC engines and gas turbines is not yet well developed.The need for on-board energy storage is discussed along with the benefits of energy management and control systems. | Yan Sun M.Anwar N.M.S.Hassan Maksym Spiryagin Colin Cole | 2021 | Railway Engineering Science2021，29，3： | 4 |
| 3 | 一系悬挂对重载货车运行影响研究显示文摘传统三大件转向架没有一系悬挂,货车运行中,短波轨道不平顺作用下轮轨中低频响应对于货车的影响较为明显。部分重载货车采用橡胶垫作为一系悬挂,降低运行时轮轨相互作用对于货车动力学性能的影响。本文以一种澳大利亚铁路重载货物运输中大量采用的30t轴重三大件转向架货车作为研究对象,参考澳大利亚铁路行业安全标准,采用多体动力学仿真分析方法,建立货车完整动力学模型,比较分析四种一系悬挂下,货车在不同线路、不同速度、不同轮轨接触条件下的磨耗指数、脱轨系数与P2力,据此分析橡胶垫垂向刚度对于货车动力学性能的影响。研究结果表明:一系橡胶垫可以有效降低干燥轮轨接触状态下货车车轮的磨耗指数与P2力,但会造成轮轨润滑状态下货车车轮的磨耗指数与P2力的增大,一系橡胶垫对于货车脱轨系数影响并不明显。 | 李春胜 罗世辉 Colin Cole Maksym Spiryagin | 2018 | 铁道学报2018，40，8： | 3 |

| 16 | Rail temperature variation under heavy haul operations显示文摘There currently does not exist in industry a reliable method for the detection of rail foot flaws.Like their head-based counterparts,foot flaws result in broken rail with potentially catastrophic consequences.A proposed area of research for the detection of these flaws is thermography,a non-contact method of measuring and analysing infrared emissions from an object under test.In industry,active excitation thermography is the most common,requiring an excitation source.This paper will present a temperature measurement system and a method of transient temperature extraction from the running rails for the effects of a passing train to evaluate heat transfer in the practical rail environment.The outcomes of these results will provide future direction in the development of a rail heat transfer model and determine if train passage provides enough active excitation for a thermography-based detection technique. | Chris Bosomworth Maksym Spiryagin Sanath Alahakoon Colin Cole Ben Sneath Bruce Makin | 2022 | Railway Engineering Science2022，30，2： | 0 |
| 17 | A review on design and testing methodologies of modern freight train draft gear system显示文摘Rolling stock connection systems are key to running longer and heavier trains as they provide both the connections of vehicles and the damping,providing the longitudinal suspension of the train.This paper focuses on the evolution of both connection and stiffness damping systems.Focus is on freight rolling stock,but passenger draw gears are also examined.It was found that connection systems have evolved from the buff and chain system used in the pioneer railways of the 1800s to the modern auto-coupler connection systems that are in-service worldwide today.Refined versions of the buff and chain coupling are,however,still in use in the EU,UK,South America and India.A wide range of auto-coupler systems are currently utilised,but the AAR coupler(Janney coupler)remains the most popular.A further variation that persists is the SA3 coupler(improved Wilson coupler)which is an alternative auto-coupler design used mainly throughout the former Soviet Union.Restricting the review to auto-coupler systems allowed the paper to focus on draft gears which revealed polymer,polymer-friction,steel spring-friction,hydraulic draft gears and sliding sill cushioning systems.Along with the single compressive draft gear units balanced and floating plate configurations are also presented.Typical draft gear acceptance standards are presented along with modelling that was included to aid in presentation of the functional characteristics of draft gears. | Simon Wagner Colin Cole Maksym Spiryagin | 2021 | Railway Engineering Science2021，29，2： | 0 |
| 18 | Recent advances in wheel–rail RCF and wear testing显示文摘The wear and rolling contact fatigue (RCF) testing approaches for wheels and rails have been reviewedand evaluated in this study. The study points out the advantages and limitations of the existing approaches. Thebroad analysis revealed that scaled laboratory-based wear testing is widely applied. However, it is necessary topredetermine the input parameters and observing parameters for scaled wear testing for three reasons: first, toemulate the real-world scenarios as closely as possible;second, to postprocess the results received from the scaledtesting and transfer them into real practice at full scale;third, to present the results in a legible/appropriate format.Therefore, most of the important parameters required for wear testing have been discussed with fundamental andsystematic explanations provided. Additionally, the transition of the parameters from the real-world into the testdomain is explained. This study also elaborates on the challenges of the RCF and wear testing processes andconcludes by providing major considerations toward successful testing. | Sundar SHRESTHA Maksym SPIRYAGIN Esteban BERNAL Qing WU Colin COLE | 2023 | Friction2023，11，12： | 0 |
| 19 | Feasibility in assessing the dipped rail joint defects through dynamic response of heavy haul locomotive显示文摘The feasibility of monitoring the dipped rail joint defects has been theoretically investigated by simulating a locomotive-mounted acceleration system negotiating several types of dipped rail defects. Initially, a comprehensive locomotive-track model was developed using the multi-body dynamics approach. In this model, the locomotive car-body, bogie frames, wheelsets and driving motors are considered as rigid bodies; track modelling was also taken into account. A quantitative relationship between the characteristics(peak–peak values) of the axle box accelerations and the rail defects was determined through simulations. Therefore, the proposed approach,which combines defect analysis and comparisons with theoretical results, will enhance the ability for long-term monitoring and assessment of track systems and provides more informed preventative track maintenance strategies. | Yan Quan Sun Maksym Spiryagin Qing Wu Colin Cole Wei Hua Ma | 2018 | Journal of Modern Transportation2018，26，2： | 0 |
| 20 | Problems,assumptions and solutions in locomotive design,traction and operational studies显示文摘Locomotive design is a highly complex task that requires the use of systems engineering that depends upon knowledge from a range of disciplines and is strongly oriented on how to design and manage complex systems that operate under a wide range of different train operational conditions on various types of tracks.Considering that field investigation programs for locomotive operational scenarios involve high costs and cause disruption of train operations on real railway networks and given recent developments in the rollingstock compliance standards in Australia and overseas that allow the assessment of some aspects of rail vehicle behaviour through computer simulations,a great number of multidisciplinary research studies have been performed and these can contribute to further improvement of a locomotive design technique by increasing the amount of computer-based studies.This paper was focused on the presentation of the all-important key components required for locomotive studies,starting from developing a realistic locomotive design model,its validation and further applications for train studies.The integration of all engineering disciplines is achieved by means of advanced simulation approaches that can incorporate existing AC and DC locomotive designs,hybrid locomotive designs,full locomotive traction system models,rail friction processes,the application of simplified and exact wheel-rail contact theories,wheel-rail wear and rolling contact fatigue,train dynamic behaviour and intrain forces,comprehensive track infrastructure details,and the use of co-simulation and parallel computing.The cosimulation and parallel computing approaches that have been implemented on Central Queensland University’s High-Performance Computing cluster for locomotive studies will be presented.The confidence in these approaches is based on specific validation procedures that include a locomotive model acceptance procedure and field test data.The problems and limitations presented in locomotive traction studies in the way they are conducted at the present time are summarised and discussed. | Maksym Spiryagin Qing Wu Oldrich Polach John Thorburn Wenhsi Chua Valentyn Spiryagin Sebastian Stichel Sundar Shrestha Esteban Bernal Sanjar Ahmad Colin Cole Tim McSweeney | 2022 | Railway Engineering Science2022，30，3： | 0 |
