Abstract

1/1 resumo “processo aperfeiçoado de detecção do desgaste de um pneumático” no decorrer do processo de detecção de desgaste de um pneumático que compreende elementos de escultura próprios para gerar um primeiro e um segundo ruídos de impressão acústica (bea1, bea2), um dos primeiro e segundo ruídos de impressão acústica (bea1, bea2) sendo característico do desgaste do pneumático, é selecionado, no espectro frequencial de um sinal acústico adquirido, um espectro frequencial pai, suscetível de formar o espectro frequencial de um dos primeiro e segundo ruídos de impressões acústicas (bea1, bea2) e um espectro frequencial fio, suscetível de formar o espectro frequencial do outro dos primeiro e segundo ruídos de impressões acústicas (bea1, bea2). são determinados dois índices de confiança, ditos de detecção. se cada índice de confiança de detecção satisfaz uma condição predeterminada, é emitido um alerta da detecção do desgaste do pneumático.
