Abstract

Una disposicion de excitacion y un método para hacer vibrar un instrumento de medicion basado en un tubo que emplea un filtro espacial para producir unasenal de excitacion que tiene contenido modal solo en un modo de vibracion deseado. Multiples sensores de realimentacion ubicados en diferentesubicaciones a lo largo de un tubo vibrante producenmultiples sensores de realimentacion. Cada senal de realimentacion tiene aplicada a la misma unfactor de ponderacion o ganancia. Todas las senales de realimentacion ponderadas son después sumadas para producir una senal de excitacion, o unasenal proporcional a una senal de excitacion, que tiene contenido modal mejorado en comparacion con cualquiera de las senales de realimentacion por símismas. Los factores de ponderacion son seleccionados por cualquiera de varios medios. El método consiste en construir la matriz de vectores característicospara el tubo de flujo vibrante extrayendo los vectores característicos de unmodelo de elemento finito de la estructura vibrante. La inversa opseudo-inversa de la matriz de vectores característicos es calculada para obtener el vector de filtro modal. El conjunto apropiado de coeficientes deponderacion es seleccionado del vector de filtro modal.
