Abstract

METODO Y APARATO PARA DETERMINAR LAS RESONANCIAS DE VIBRACION DE LOS ALABES DE UNA TURBOMAQUINA. SE DESCRIBE UN APARATO Y SU METODO PARA CARACTERIZAR LAS RESPUESTAS DE RESONANCIA DE UNA PLURALIDAD DE ALABES GIRATORIOS (22) EN UNA TURBOMAQUINA (12). EL SISTEMA INCLUYE UNA PLURALIDAD DE CHORROS DE FLUIDO CONTROLABLES (16) DISPUESTOS ALREDEDOR DE UNA HILERA DE ALABES PARA EXCITAR LOS ALABES GIRATORIOS (22) CON FRECUENCIAS DE VIBRACION QUE PUEDEN SER ELEGIDAS. LA EXCITACION SECUENCIAL DE LOS ALABES A UNA PLURALIDAD DE FRECUENCIAS SIMULTANEA POR UN INTERVALO ESTRECHO Y LA DETECCION SIMULTANEA DE LAS RESPUESTAS DE LOS ALABES PERMITE DETERMINAR SUFICIENTEMENTE LAS FRECUENCIAS CENTRALES DE RESONANCIA Y SUS ARMONICAS PARA DETECTAR LOS CAMBIOS EN LAS RESONANCIAS CARACTERISTICAS DE LOS ALABES.
