Popis: International audience; The contribution o fgear tooth flank surface micro-finish on gear noise has not yet been taken intoconsideration. This paper is devoted to study the simultaneous effect of tooth roughness and lubricantviscosity on automotive gear vibrations.The vibrations performances were evaluated on an instrumentedtest rig under both dry and wet conditions. A non-destructive replication technique coupled to 3D opticalmeasures was used to acquire the flanks topographies,which were characterized using multiscaledecomposition. A three-dimensional finite element simulation of a helical gear was performed to assessthe micro-scales impact on gear noise.Numerical representative surfaces morphologies were introducedinto the simulation and compared through the transmission error calculation. Results have shown gearnoise dependence on tooth finishing processes.
