Abstract

SE PRESENTA UN APARATO Y METODOS CONEXOS PARA CAPTURAR UNA IMAGEN DIGITAL DE LA HUELLA UN NEUMATICO Y EXTRAPOLAR LAS CURVAS DE CARGA-FLEXION DEL NEUMATICO. UN BASTIDOR SOPORTA UNA CAJA DE PRUEBAS ACOPLADA A UN NEUMATICO PARA REALIZAR DIVERSAS PRUEBAS. EN UNA APLICACION, UNA PLACA DE CARGA ACOPLA EL NEUMATICO A UNA PLACA TRANSPARENTE EN LA CAJA DE PRUEBAS DONDE UNA CAMARA CAPTURA UNA IMAGEN DIGITAL EN ESCALA DE GRISES DE LA HUELLA DEL NEUMATICO. UN PROCESADOR CONVIERTE LA IMAGEN EN ESCALA DE GRISES EN UN MAPA DE PRESIONES EN EL QUE CADA PIXEL DE LA IMAGEN DIGITAL SE CORRELACIONA CON UN VALOR DE PRESION. EN OTRA APLICACION LA PLACA DE CARGA ACOPLA EL NEUMATICO A UNA PLACA DE CUBIERTA DESLIZANTE SITUADA SOBRE LA CAJA DE PRUEBAS, Y LA CARGA DE LA PLACA DE CARGA SE INCREMENTA EN UNA SERIE DE VALORES DE CARGA A PRESIONES DE INFLADO PREDETERMINADAS. UTILIZANDO DOS PRESIONES DE INFLADO EL PROCESADOR EXTRAPOLA MAS CURVAS DE CARGA-FLEXION DEL NEUMATICO A OTRAS PRESIONES DE INFLADO. EL APARATO PROPORCIONA TAMBIEN UN MEDIO EXCLUSIVO DE IMPARTIR ANGULO DE CAIDA AL NEUMATICO DURANTE LAS PRUEBAS ANTERIORES. LOS DATOS RECOGIDOS DE LA IMAGEN DE LA HUELLA Y DE LAS CURVAS DE CARGAFLEXION PUEDEN UTILIZARSE PARA ANALIZAR LA ESTRUCTURA, FUNCIONAMIENTO, CARACTERISTICAS DE PRODUCCION DE RUIDO Y RENDIMIENTO DEL NEUMATICO.
