Based on the models, the changes of track geometry of the two track structures were studied, the mechanical behaviour of track components was revealed, and the effect of irregularity caused by fault dislocation on vehicle dynamic response was studied. Results show that the components of CRTS III slab track are damaged at a smaller dislocation displacement than those of prefabricated-polyurethane reinforced ballasted track. With the increase of the train speed and dislocation displacement, the derailment coefficient and wheel load reduction rate also increase. The safe speed limits for travelling under different types of fault and different dislocation displacements are obtained, which can provide reference for similar engineering applications.KEYWORDS: Prefabricated-polyurethane reinforced ballasted trackballastless trackactive fault zonemechanical behaviourvehicle dynamic response Disclosure statementNo potential conflict of interest was reported by the authors.Data availability statementData will be made available on request.CRediT authorship contribution statementWei Chen: Conceptualization, Methodology, Software.

Mechanical tests were conducted to determine the mechanical properties of the material of the bogie frame while a combination of machine learning and FEA has been utilized to generate a dataset for the dynamic response of the bogie frame under main in-service fatigue loads. Nine machine learning-based surrogate models were constructed based on the actual response at a limited set of data points chosen by the Optimum space-filling algorithm, and their accuracy was investigated. It is found that the CatBoost model is the optimal algorithm to map the stochastic input parameters with the factor of safety as the output parameter and perform the reliability evaluation. Also, results reveal a fatigue reliability of 99.34% for the bogie frame under normal conditions, with a cumulative failure probability of less than 0.66% over a 30-year service life. Furthermore, the results show that the proposed machine learning-based approach is an efficient tool to evaluate the fatigue failure probability of the bogie frame with reasonable accuracy when a small set of training data is available. This study’s scope extends to providing comprehensive guidelines for employing machine learning methods for fatigue reliability analysis of complex vehicle structures in the presence of various stochastic variables.KEYWORDS: Bogie framefatigue failure probabilitystructural reliabilitymachine learningsurrogate modelFEM Disclosure statementNo potential conflict of interest was reported by the authors.Author contributionsSeyed Ahmad Sanikhani: Investigation, Methodology, Software, Visualization, Formal Analysis, Writing – Reviewing and Editing.

Firstly, this work assesses the traditional transition structures, including horizontal and inclined approach slabs and transition wedges, using commonly studied responses (kinematic response and stress) and a recently proposed criterion based on total strain energy minimization. The second part of the paper evaluates the newly introduced transition structuress (SHIELD) using the same criterion as used for the evaluation of the traditional transition structures. A detailed investigation of existing and a new design using a 2-dimensional finite element model shows SHIELD’s effectiveness in managing energy flow at transition zones and provides reasoning behind the ineffectiveness of the other commonly used transition structures. The study demonstrates the robustness and comprehensiveness of the recently developed energy-based criterion and its applicability to different types of transition zones. Moreover, it highlights the potential of SHIELD as a solution to address the complexities associated with the design of railway transition zones.","PeriodicalId":48510,"journal":{"name":"International Journal of Rail Transportation","volume":"113 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135017839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One approach to braking in high-speed trains is using aerodynamic plate brakes, which offer improved braking performance at high speeds but can impact the train’s aerodynamic characteristics. In this study, dynamic grid technology was used to achieve plate motion, and unsteady Reynolds-averaged Navier-Stokes (URANS) equations and shear stress transfer (SST) k-ω turbulence model were adopted to simulate the unsteady aerodynamic behaviour of a 5-car maglev train running at 600 km/h. Two wind tunnel experiments validated the method, and grid independence analysis was also conducted. The unsteady aerodynamic performance and transient flow field around the train during plate braking in tailwind and headwind opening configurations were studied and analysed. As the plates opened, there was a rapid increase in both aerodynamic drag and lift, creating a pulse-like change. The tailwind opening configuration generated relatively large peak aerodynamic forces, whereas the peak forces decreased successively downstream along the train length. As the flow stabilized, periodic fluctuations in the aerodynamic forces of the plates occurred. The interference with the convective field and the impact on the aerodynamic force of the tail car were more significant for the tailwind opening configuration. In addition, the tailwind opening plate caused significant fluctuations in the aerodynamic force of the tail car, with similar effects observed in other cars. From an aerodynamic perspective, the headwind opening configuration yielded better results. These findings can guide the design and implementation of plate brakes for high-speed maglev trains.KEYWORDS: High-speed maglev trainopen directionaerodynamic plate brakingunsteady aerodynamic behaviourflow field Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe datasets used and/or analysed during the current study are available from the corresponding author on reasonable request.Additional informationFundingThis study was supported by the Key R&D Program of Shandong Province (Major Scientific and Technological Innovation Project) [2020CXGC010202], Fundamental Research Funds for the National Natural Science Foundation of China [52172359 and 52372363].","PeriodicalId":48510,"journal":{"name":"International Journal of Rail Transportation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135316515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies have focused on establishing guidelines for evaluating the condition of ballasted tracks. Light Falling Weight Deflectometer (LFWD) is considered as a quantitatively viable technique for conducting routine maintenance checks in Korea, serving as a potential replacement for impact sound assessment. LFWD measures the impact force applied to the sleeper and the resulting deflection, which provides the apparent stiffness and damping factor of the ballasted track. Finite element analysis (FEA) was adopted to simulate the LFWD tests as the ballasted tracks deteriorated. The FEA results revealed the influence of the deteriorated ballasted tracks on the stiffness-damping relationship. The characteristic curves of the apparent stiffness and damping factor derived from FEA were applied to investigate the condition of 12 ballasted tracks for high-speed trains in Korea.
