Abstract

METODO DE DETECCION DE DEFECTOS INTERNOS EN CUBIERTAS DE NEUMATICO Y APARATO CORRESPONDIENTE, DE MANERA NO DESTRUCTIVA, PARA FABRICAR NEUMATICOS RECAUCHUTADOS, HACIENDO GIRAR LA CUBIERTA INFLADA A VELOCIDAD CONSTANTE A LA VEZ QUE SE PRESIONA UN SENSOR DE DESPLAZAMIENTO CONTRA LA SUPERFICIE EXTERIOR PARA DERIVAR DOS JUEGOS DE SEÑALES, DERIVANDO DIFERENCIAS ENTRE LAS SEÑALES EN LOS PUNTOS DE MEDICION EN DICHA SUPERFICIE, DERIVANDO UN VALOR DE DESPLAZAMIENTO MINIMO, CALCULANDO DESVIACIONES ENTRE EL VALOR MINIMO Y LAS DIFERENCIAS DE DESPLAZAMIENTO. SE DERIVA UNA DESVIACION MAXIMA Y SE COMPARA CON UN PRIMER VALOR UMBRAL. MEDIANTE LA COMPARACION DE LOS DISTINTOS VALORES HALLADOS LOS DISTINTOS UMBRALES Y LA MEDIA DE LOS VALORES, SE PUEDE JUZGAR SI LA CUBIERTA ADOLECE DE DEFECTOS INTERNOS SUFICIENTES PARA DETECTAR SU RECHAZO. SE DESCRIBE TAMBIEN UN APARATO PARA LA REALIZACION DEL METODO.
