Transposició de model a prototipus de les freqüencies pròpies d'estructures submergides.

Transposició de model a prototipus de les freqüencies pròpies d'estructures submergides.

Abstract

Aquest treball consisteix en determinar les freqüències pròpies d’un cos submergit proper a una superfície, amb l’objectiu de trobar si existeix una relació quan el conjunt s’escala. Tot i que pot ser útil per a varies aplicacions, aquest projecte es centre en estudiar si es poden extrapolar de model a prototipus les freqüències pròpies del rodet d’una màquina hidràulica tipus Francis. Per determinar les freqüències pròpies de les geometries analitzades s’han utilitzat les branques Modal i Modal Acoustics del programari ANSYS. En la memòria es recull la configuració dels models, els resultats obtinguts i les conclusions extretes, així com un context teòric previ de màquines hidràuliques i vibracions mecàniques
