Abstract

"MELHORIAS NOS TESTES DE UNIFORMIDADE DOS PNEUS". Descreve-se um processo e aparelho para testes de pneu. Na etapa (110), a variação de força radial é medida na direção atual de rotação. O primeiro harmónico dessa variação de força é calculado na etapa (120), e uma posição de pneu correspondente ao cruzamento pelo zero do primeiro harmónico é determinada na etapa (130). Na etapa (140), a posição do pneu é monitorada, até que um cruzamento pelo zero seja alcançado. A direção de rotação é invertida no local apropriado na etapa (150), e o teste tem prosseguimento.
