The purpose is to explore the three-sleeper tamping operation mechanism maintenance. First, a model of the interaction between tamping picks and ballast particles was proposed. Then, the model of three-sleeper tamping operation was established by discrete element method (DEM) and multibody dynamics (MBD) coupling approach. Finally, the macro–meso properties of ballast particles was analysed. The results indicate that the tamping operation can considerably reduce the compactness of the ballast bed in the bottom of the sleeper and the crib area and also disturb the ballast shoulder area. In the penetration stage, there is a critical position of normal contact force of ballast particles. Moreover, the ballast at the bottom of the sleeper can move to either side of the sleeper during the rotation stage of the retracting, which is not conducive to the compaction.","PeriodicalId":48510,"journal":{"name":"International Journal of Rail Transportation","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45880105","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}

By injecting a series of linearly independent wideband excitation signals, the SFCAs of train are obtained simultaneously without affecting the network impedance. Considering the frequency distribution of wideband signal, an alternating injection method based on multi-tone signal is proposed. It aims at eliminating the overlapping effects of various frequency relationships on the target coupling harmonics in the 4QC control system. With unknown network impedance, the SFCAs of train covering all the desired frequencies, even several times sampling frequency, can be captured by the proposed wideband measurement approach. Comprehensive experiments are conducted on a hardware-in-the-loop (HIL) system for validating the measurement results.","PeriodicalId":48510,"journal":{"name":"International Journal of Rail Transportation","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43032338","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}

The study, which uses the Virginia Tech-Federal Railroad Administration (VT-FRA) roller rig, extends past tribological studies with twin disks. Separate tests are performed in two phases. In Phase 1, the effect of TORFM volume, ranging from light to heavy applications (about 1 to 25 μm layer thickness), is evaluated on wheel wear. The normalized results indicate that light applications of TORFM yield the most favourable wear-to-cost ratio. In Phase 2, TORFM effectiveness duration is evaluated by applying the material in multiple cycles and monitoring the time-lapse for adhesion to recover to the unlubricated condition. Repeated applications of TORFM in moderate amounts (5 μm layer thickness) could lead to a stick-slip phenomenon that could not only diminish adhesion but also lead to surface markings on the rail.","PeriodicalId":48510,"journal":{"name":"International Journal of Rail Transportation","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44666969","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}

Previous treatment of EPC as linear elastic material was insufficient in the failure analysis of ERS. In this work, a hyperelastic model is developed to describe the mechanical properties of the EPC with engineering strain up to 150%. Physical tests of uniaxial tension, planar tension and quadruple shear are conducted. A 4-parameter Ogden model is determined by curve fitting and validated with a progressive validation strategy, and then is applied to the failure analysis of ERS. It is found that the material nonlinearity of EPC contributes noticeably to the decrease of the longitudinal stiffness of ERS. The 2nd debonding is more probably caused by the failure of adhesive at the interface between EPC and rail rather than EPC itself.","PeriodicalId":48510,"journal":{"name":"International Journal of Rail Transportation","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2022-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46083692","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}

A reliable rail wear prediction model to evaluate the evolution of the rail profile should be developed. In this study, a rail wear prediction model for a metro line is established. The vehicle system dynamics model is implemented in the SIMPACK software, which considers the actual operating conditions of the metro line. The results show that using the original Tγ/A wear rate function to calculate rail wear may yield some deviations, which necessitates a modification of the wear model based on the measured results of rail wear. Because the hardness of high and low rails on curved tracks changes after work hardening, different correction coefficients must be adopted for the wear rate function of each rail. The rail wear evolution and worn profiles are consistent with the field measurement results when using a modified wear function.","PeriodicalId":48510,"journal":{"name":"International Journal of Rail Transportation","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46869457","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}

However, the heavy computation pressure caused by high-efficiency requirements, massive passengers, and high network complexity makes it more challenging to integrate passenger and train traffic simulation into a unified model. We propose an efficient multi-agent model to simultaneously simulate passenger and train traffic in the URT network. The model framework comprises several agents, including passenger batch, train, line, and network. A passenger aggregation method is proposed to release the computation pressure. The model is tested in the URT network of Chongqing, China. The experiment results show the model can handle a 1.6 million passengers, 1900 trains simulation within 86 s, without losing any passengers’ specific travel spatial and temporal trajectory. Three experiments are conducted for further validation, including analysing the transportation performance under different passenger route assignments, train headways, and AFC data, respectively.","PeriodicalId":48510,"journal":{"name":"International Journal of Rail Transportation","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48464586","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}
