Abstract

SE DESCRIBE UN PROCESO PARA EL CONTROL DE CALIDAD DE UNA ESTRUCTURA MONTADA (2) CON UN ANILLO DE MATERIAL ELASTOMERICO (3) ACOPLADO ENTRE UN COLLAR METALICO INTERNO (4) Y OTRO EXTERNO (5) Y QUE ESTA MECANICAMENTE ESTRESADO DE MANERA QUE SOPORTA UNA DEFORMACION ELASTICA CORRESPONDIENTE A UN DESPLAZAMIENTO DE 15 MM ENTRE LOS COLLARES, DURANTE UN TIEMPO DE 20 SEGUNDOS. UNOS TRANSDUCER ACUSTICOS (7) PREVIAMENTE ACOPLADOS A LA ESTRUCTURA (2) DETECTAN LAS EMISIONES ACUSTICAS QUE OCURREN DENTRO DE LA ESTRUCTURA, ORIGINADAS POR LA INESTABILIDAD DE ESTA DEBIDAS A DEFORMACIONES. LOS TRANSDUCER CONVIERTEN LAS EMISIONES ACUSTICAS EN SEÑALES ELECTRICAS DE TAL MANERA QUE UNOS AMPLIFICADORES Y DISCRIMINADORES FILTRAN LOS DATOS PARA LA EVALUACION DE LA ESTRUCTURA.
