Abstract
UN MONITOR PARA FATIGA VIBRATORIA EN LINEA MIDE EWL DESPLAZAMIENTO DE UN OBJETO TAL COMO UN ALABE DE UN ROTOR DE TURBINA QUE GENERA UNA SEÑAL DE DESPLAZAMIENTO PRODUCIDA POR LA PROXIMIDAD DE LOS SENSORES Y QUE CALCULA LA FATIGA ACUMULADA EN EL OBJETO EN DEPENDENCIA SOBRE EL DESPLAZAMIENTO DE LA SEÑAL. LAS SEÑALES SE DIGITALIZAN Y PROCESAN, MEDIANTE UN TRANSFORMACION HILBERT, PARA DETECTAR EL DESARROLLO DE AMPLITUD Y FRECUENCIA INSTANTANEA DEL DESPLAZAMIENTO. LA AMPLITUD Y FRECUENCIA SE COMBINAN CON TENSIONES DE ESTADO ESTABLE SOBRE EL OBJETO PARA DETERMINAR LA FATIGA QUE SE ACUMULA POR DESPLAZAMIENTO VIBRATORIO DE PROCESAMIENTO CONSTANTE Y CAMBIO EN EL ESTADO DE TENSION.
