These cars are connected together to form a train, and they play a crucial role in facilitating the transportation of goods and people across railway networks worldwide.
...ght maintenance criteria. However, these usually do not consider the vehicle dynamics and the geometry of the permanent way together. Thus, this paper develops a mathematical model of a high capacity railcar together with the flexibility of the support of the permanent way. The mathematical model was validated and considered satisfactory, by comparing the natural frequencies obtained between the model an...
...sempre justos. Entretanto, estes critérios geralmente não contemplam de maneira conjunta a dinâmica veicular e a geometria da via permanente. Neste sentido, este trabalho elabora um modelo matemático de um vagão ferroviário de alta capacidade em conjunto com a flexibilidade do suporte da via permanente. O modelo matemático foi validado e considerado satisfatório, a partir da comparação das frequências naturais obtidas no vagão real e na comparação de seu resultado produzido a partir de um...
