| dc.description | —El estudio que se presenta tratará sobre el
comportamiento dinámico que existe ante la transición que se
produce a la entrada y salida de un túnel cuando en este último se
ha instalado catenaria rígida mientras en el exterior se mantienen
sistemas de catenaria flexible. La viga de transición utilizada es
un elemento que pretende mitigar las diferencias dinámicas en
la fuerza del contacto que se produce entre ambos tipos de
catenaria. Su geometría está basada en la viga de rígida, teniendo
el mismo perfil inicial y reduciendo su sección para disminuir la
rigidez. Los mecanismos actuales de catenaria rígida y transición
no permiten el paso a velocidades por encima de 100 km/h,
produciéndose pérdidas de contacto y arcos eléctricos que
aumentan el desgaste de los componentes considerablemente. El
presente trabajo se centra en la caracterización del comportamiento
dinámico de los sistemas de transición actuales entre tipos de
catenaria y propone una configuración alternativa que permita
reducir la pérdida de contacto entre componentes para velocidades
por encima del límite conocido. Esto permitirá aumentar el rango
de velocidades de explotación y la instalación de catenaria rígida en
un mayor ámbito, reduciendo las necesidades de galibo y en
consecuencia el diámetro de los túneles a crear | en_US |
| dc.description.abstract | The study presented will deal with the dynamic behavior
that exists before the transition that occurs at the entrance and exit
of a tunnel when a rigid catenary has been installed in the latter
while flexible catenary systems are maintained abroad. The
transition beam used is an element that aims to mitigate the
dynamic differences in the strength of the contact that occurs
between both types of catenary. Its geometry is based on the rigid
beam, having the same initial profile and reducing its section to
reduce stiffness. The current rigid catenary and transition
mechanisms do not allow passage at speeds above 100 km / h,
resulting in loss of contact and electric arcs that increase the wear
of the components considerably. This paper focuses on the
characterization of the dynamic behavior of current transition
systems between types of catenary and proposes an alternative
configuration that allows reducing the loss of contact between
components for speeds above the known limit. This will allow
increasing the range of operating speeds and the installation of
rigid catenary in a larger area, reducing the needs of gauge and
consequently the diameter of the tunnels to be created.
