Resumen
La investigación llevada a cabo tiene la finalidad de generar una metodología sencilla y eficaz en la obtención de la carga producida por uno de los efectos aerodinámicos del viento conocido como galope transversal. Para ello se llevó a cabo un estudio de la aerodinámica civil, donde se profundiza el estado del arte del galope transversal, la clasificación de las variables que influyen en esta inestabilidad aeroelástica y los tipos de estructuras susceptibles. Esto finalmente permitirá generar un procedimiento de cálculo estandarizado que permita la obtención de la carga galope transversal de forma estática y mediante un sistema de cargas distribuidas sobre secciones transversales. Para la verificación de resultados se evalúa la influencia del galope transversal en una estructura tipo enrejado (correa transportadora), a través de un modelo estructural computacional y la aplicación del procedimiento determinado y definido, de manera de establecer los elementos que tienen una mayor susceptibilidad al efecto generado. Esto último desde el punto de vista local como global que puede tener sobre cualquier superestructura.
The research carried out has the purpose of generating a simple and effective methodology in obtaining the load produced by one of the aerodynamic effects of the wind known as transverse gallop. For this purpose, a study of civil aerodynamics was carried out, which explores the state of the art of the transverse gallop, the classification of the variables that influence this aeroelastic instability and the types of susceptible structures. This will finally allow the generation of a standardized calculation procedure that allows obtaining the cross gallop load in a static way and through a system of distributed loads on cross sections. For the verification of results, the influence of the transverse gallop on a lattice-type structure (conveyor belt) is evaluated, through a computational structural model and the application of the determined and defined procedure, in order to establish the elements that have a greater susceptibility to effect generated. The latter from the local as well as global point of view that it can have on any superstructure.
