Повний текст джерелаThe appearance of dynamic phenomena during the running of train on track leads to issues such as noise and vibration pollution, which can be further amplified by the presence of defects on the treads. In order to analyze them, it is necessary to predict with reliability the dynamic behavior of the vehicle-track interaction components, in particular the contact forces produced by non perfect treads.The aim of this PhD thesis is to provide a semi-analytical vehicle-track interaction model able to take into account multiple defects on the surfaces in contact. In order to conduct simulations in the time-domain and ensure applicability in the sizing phase, a special attention is given on the compromise between the accuracy of the results and the simulation times.The proposed model is therefore composed of half a bogie running on a ballasted track. This latter is modeled by a pinned-pinned beam with periodic supports located at the sleepers while the vertical behavior of the bogie is given by masses, springs and dampers. These two models are coupled in contact by a discretized Distributed Point Reacting Spring (DPRS) procedure.A validation of the model, based on previous work, is firstly proposed for perfect treads. Then, multiple combinations of defects, either localised as wheelflat or spread as corrugation, are introduced in the simulation. The spatial variability, specific to shelling, is modeled by random fields

Повний текст джерелаSouth Africa’s railway system is the most highly developed in Africa. There are different kinds of transport systems in South Africa but rail transport is considered as one of an important element of the country’s transport infrastructure. In South Africa, over 2.4 million passengers make use of rail transport to get them to their destinations. However, evidence shows that train accidents have become a common occurrence across the country. Train-related accidents such as collision, derailments, platform change incidents and commuter accidents, cost South Africa over R400 million per year. The analysis of derailments indicates that the most significant single contributor to derailments is rail breaks. This contrasts considerably with prescribed relevant local and international benchmarks, which show a much lower percentage of derailments due to rail break. The frequency of derailments due to rail breaks in South Africa seems to be higher in the northern than the southern region. Furthermore, the proportion of rail breaks that result in derailment is considerably higher than the set benchmarks and therefore, if there is a rail break, then the probability of this translating into a derailment is astonishingly high. Equally, the high incidence of derailments due to rail breaks is affected by the train length and axle load and further exacerbated by the absence of track circuitry. Since derailments are a direct function of the incidence of rail breaks, focus is required to characterize the factors causing defects on rail lines. This study investigated steel rail material by characterising the piece of the damaged rail with the aim to gain a better understanding of the wear mechanism. Chemical composition analysis of steel rail sample was conducted with the use of a Scanning Electron microscopy. Hardness of steel rail was measured with a Vickers hardness tester. An Optical Microscopy was used to examine the microstructure features of the worn rail samples. This study discovered that the worn out rail, which was produced from high carbon steel with pearlite and ferrite microstructure, undergoes decarburization and a plastic deformation process. The decarburization process happens when the rail track is heated to 700 oC and above when the carbon atoms at the surface interact with the atmospheric gases and are removed from the steel as a gaseous phase. Plastic deformation is created when the iron atoms are heated above the elastic point resulting in the permanent movement of iron atoms.

Resumo: O assunto a ser abordado nesta pesquisa refere-se ao componente da superestrutura ferroviária trilho, especificamente aos defeitos que nele se verificam em conseqüência de sua utilização como guia para o material rodante e transmissor de esforços decorrentes do movimento do veículo, e do desgaste do contato roda-trilho. A importância de se realizar este estudo fundamenta-se na necessidade de se conhecer detalhadamente os defeitos e o limite de desgaste do trilho, que permitem determinar sua vida útil, para que se possa evitar ao máximo sua substituição, devido ao alto custo envolvido, além da questão da segurança da via que, dependendo do defeito, pode ser comprometida. Para a realização do trabalho foi realizada uma pesquisa bibliográfica, objetivando reunir informações sobre o assunto e levantar dissertações existentes que buscam solucionar tais problemas. Busca-se, ainda, encontrar uma justificativa para o valor limite de desgaste adotado atualmente no meio ferroviário, que corresponde a 25% de perda em área do boleto do trilho, através de simulações do desgaste utilizando-se um modelo computacional, além de rotinas de cálculo que permitam verificar se esse parâme1rO é restrição do . ponto de vista do dimensionamento do trilho. Pretende-se, assim, a1ravés desta pesquisa proporcionar uma contribuição ao meio ferroviário, avaliando-se se o limite de desgaste adotado mos1ra-se adequado à realidade ferroviária
Abstract: The matters concerned in this research particularly refer to damages caused by stress while using tracks on permanent railways as guide and strain transmitter of the vehicles. Importance is attached to this study based on the need of understanding deep and in detail the faults and wear limits on the tracks, which allow determining its period of use, so that substitution may be avoided due to its high costs. Furthermore, the railway safety may be weaknessed depending on the sort of wear. This study has basis on a bibliographical research aiming to gather information and possible works on this field in order to solve the problems mentioned above, as well as finding proofs for the current wear rate accepted in the railway field, which is 25% of track area decrease, throughout wear simulations on a computer based model, besides calculations which allow stating whether this standard depends on the track size. This work claims to contribute to the railway field evaluating if the adopted wear rate meets our railway reality
