Coupled computation of meshing and bearings stiffnesses : effect on radiated gearbox noise
François Mayeux, Joël Perret-Liaudet, Emmanuel Rigaud
This study focus on the acoustical behavior of gearbox induced by the static transmission error under load (STE). An original method is developed allowing to compute simultaneously…
Dispersion of critical rotational speeds of gearbox: effect of bearings stiffnesses
François Mayeux, Emmanuel Rigaud, Joël Perret-Liaudet
Noise measurement on a population of a gearbox manufactured in large number reveals a high variability principally due to tolerances on each design parameter of the gear. Gearbox n…
Effect of an original gear mesh modelling on the modal behaviour of gear transmission
Emmanuel Rigaud, Joël Perret-Liaudet, Mohamed-Salah Mecibah
Prediction of the vibroacoustic behaviour of geared transmissions is generally based on determining the excitation sources, the overall modelling of the transmission, the modal ana…
