Abstract

METODO PARA ELIMINAR LOS EFECTOS DEL MOVIMIENTO DE LOS SENSORES EN UN SISTEMA DE SUPERVISION DE VIBRACIONES. SE DESCRIBE UN METODO PARA ELIMINAR LOS ERRORES DE LOS DATOS DE POSICION-TIEMPO PROPORCIONADOS POR UN APARATO QUE SUPERVISA LA POSICION DE UN ALABE GIRATORIO (BI) EN UNA TURBOMAQUINA EN FUNCION DE UNA ROTACION PERIODICA, INCLUYENDO EL APARATO, UN SENSOR (SJ) PARA PROPORCIONAR UNA SEÑAL DE TIEMPO QUE CORRESPONDE AL TIEMPO REAL DE LLEGADA NECESARIO PARA QUE UN ALABE (BI) SE DEPLACE DESDE UNA POSICION PREDETERMINADA HASTA LA POSICION DE UN SENSOR (SJ), SIENDO PRODUCIDOS LOS ERRORES POR UNA FALTA DE ALINEACION O EL MOVIMIENTO DE POR LO MENOS UN SENSOR (SJ) CON RESPECTO A UN ALABE GIRATORIO (BI). EL METODO INCLUYE LAS OPERACIONES QUE CONSISTEN EN CALCULAR EL TIEMPO MEDIO DE LLEGADA DEL ALABE (BI) PARA EL MOVIMIENTO DEL ALABE (BI) DESDE LA POSICION PREDETERMINADA HASTA UN SENSOR (SJ) CON RELACION A LA POSICION PREDETERMINADA, BASANDOSE EN LA VELOCIDAD DEL ALABE (BI) Y EL TIEMPO DE LLEGADA.
