Avaliação em laboratório do efeito da formulação e das propriedades de graxas lubrificantes no desempenho tribológico do contato roda-trilho
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2020-08-14)
Tribological phenomena in the wheel-rail interface are complex. In sharp curves, the severe contact conditions lead to high values of friction and wear. Excessive friction increases fuel consumption (highest material cost ...
