Abstract

LA INVENCION SIRVE PARA LA DETERMINACION PARTICULARMENTE EXACTA DEL LUGAR DE UNA FUGA EN UN COMPONENTE CONDUCTOR DE PRESION. PARA ELLO SE SUBDIVIDE EL TRAMO A COMPROBAR EN SEGMENTOS (A, B, C), DENTRO DE LOS CUALES EXISTE CADA VEZ EL MISMO COEFICIENTE DE AMORTIGUACION DEL SONIDO. DENTRO DE LOS SEGMENTOS (A, B, C) SE MIDE CADA VEZ EN PUNTOS DE MEDICION PREFIJADOS (X1,X2, ...) CON AYUDA DE UN SENSOR DE ULTRASONIDOS EL NIVEL DE SONIDO (EL2), EL CUAL DISMINUYE EN LA FUGA. EN UN DIAGRAMA DE BARRAS, SE REPRESENTAN LOS NIVELES DE SONIDO (EL2) POR MEDIO DE COORDENADAS EFECTIVAS DEL LUGAR (X1, X2, ...). ESTAS COORDENADAS EFECTIVAS DEL LUGAR (X1, X2, ...) RESULTAN DE LAS COORDENADAS DEL LUGAR DE LOS PUNTOS DE MEDICION (X1, X2, ...) POR CONSIDERACION DE CADA COEFICIENTE DE AMORTIGUACION ((ALFA)1, (ALFA)2, (ALFA)3). LAS COORDENADAS EFECTIVAS DEL LUGAR (X1, X2, ...) ESTAN SOBRE UN EJE (X), CUYOS SEGMENTOS ((ALFA)1A, (ALFA)2B, (ALFA)3C) RESULTAN POR MULTIPLICACION DE LOS SEGMENTOS LONGITUDINALES (A, B, C)POR LOS CORRESPONDIENTES COEFICIENTES DE AMORTIGUACION ((ALFA)1, (ALFA)2, (ALFA)3). EL PUNTO DE INTERSECCION (P) DE DOS RECTAS DE COMPENSACION (G1,G2) EN ESTE DIAGRAMA CARACTERIZA EL LUGAR DE LA FUGA (XL). SE LE OBTIENE POR CALCULO DE REGRESION BAJO CONSIDERACION DE LOS CORRESPONDIENTES COEFICIENTES DE AMORTIGUACION ((ALFA)1). EL EQUIPO COMPRENDE UN ORDENADOR.
