Abstract(s)
O trabalho descreve as tecnologias e as regras afectas aos aparelhos de mudança de via
instalados em linhas ferroviárias, as finalidades e os postulados normalizados destes, os
seus elementos constituintes, as cotas mais importantes, a escala e o cálculo das
velocidades, bem como a insuficiência de escala admissível destes.
Procura ainda dar um exemplo prático de um encurvamento e dimensionamento
geométrico de uma comunicação de via com entre eixo de 3808mm (E.E.=3808),
formada por dois aparelhos de mudança de via simples (MVS´s), que foram aplicados
na estação de Coimbra B.
Serão calculadas e definidas as velocidades para a comunicação formada e para cada
um dos dois aparelhos de mudança de via simples que constituem esta.
Por fim, serão discutidas as velocidades permitidas pela comunicação formada, bem
como serão propostas melhorias à referida comunicação de via de forma a esta permitir
maiores velocidades.
The work describes the technologies and rules related to the turnouts installed on railways lines, their purposes and standard postulates, their constituent elements, the most importante dimensions, the cant and calculation of speeds, as well the cant deficiency permissible of these. It also seeks to give a practical exemple of a bended and geometric dimensioning of a crossover with 3808mm between axis (E.E.=3808), formed by two turnouts, which were applied at the railway station of Coimbra B. The speeds will be calculated and defined for the crossover formed and for each turnout that constitute it. Finally, will be discussed the speeds allowed at the formed crossover, as well will be proposed improvements to the referrred crossover in order to allow higher speeds.
