Abstract

"MéTODO DE CONTROLE DO FUNCIONAMENTO DE UM PNEUMáTICO". Método de controle do funcionamento de um pneumático, que consiste em determinar estimativas ou medições do deslizamento G~ i~ e do coeficiente de aderência <109>~ i~ que existe no dito deslizamento, para pelo menos um par de valores (G~ i~, <109>~ i~); determinar os valores correspondentes da inclinação <244>~ i~, da reta que passa pela origem e por (G~ i~, <109>~ i~); calcular um coeficiente B por cálculo direto ou por uma regressão a partir de um número suficiente de pares com (<244>~ i~, G~ i~) de modo a estimar o valor de <244>~ 0~ na origem; utilizar <244>~ 0~ como indicador do valor da rigidez longitudinal de escultura; deduzir a altura residual de escultura do valor da rigidez longitudinal de escultura, daí um indicador de desgaste do pneumático.
