Abstract

"MéTODO PARA MEDIR PROPRIEDADES CARACTERìSTICAS DE UM PNEU PARA RODAS DE VEICULO". Um método para medir propriedades características de um pneu (2) para rodas de veículo, compreende as etapas de arranjar, pelo menos, um sistema de sensores (10) ao longo de uma direção y transversal a uma direção de movimento x do pneu (2), fazer o pneu (2) passar em velocidade sobre, pelo menos, um sistema de sensores (10) ao longo de dita direção x, detectar a velocidade de deformação de cada sensor (10), gerar para cada sensor (10) um sinal elétrico proporcional à dita velocidade de deformação e determinar, partindo de cada sinal elétrico detectado, pelo menos uma propriedade de característica do pneu (2), por exemplo, a dimensão e/ou a forma da área de impressão do pneu (2). Integrando no tempo o sinal elétrico, é então possível determinar a distribuição de pressão sobre tal área de impressão. Os sensores (10) compreendem elementos piezelétricos, que sendo conhecidos por terem resposta em alta freq³ência, permitem detecção em condições de alta velocidade.
