Response of an impacting hertzian contact to an order-2 subharmonic excitation : theory and experiments
Joël Perret-Liaudet, Emmanuel Rigaud
Response of a normally excited preloaded Hertzian contact is investigated in order to analyze the subharmonic resonance of order 2. The nonlinearity associated with contact losses…
Gearboxes: indirect identification of dynamic forces transmitted to housing through bearings
Gu Xiang Zhang, Emmanuel Rigaud, Jean-Claude Pascal +1
In order to determine indirectly the generalized forces applied on the gearbox, two approaches are tested, one is a numerical method, the other is experimental. For the numerical m…
Variability of Critical Rotational Speeds of Gearbox by Misalignement and Manufacturing Errors
N. Driot, Emmanuel Rigaud, Joël Perret-Liaudet
Noise measurement on a population of gearbox manufactured in large number often reveals high variability due to tolerances on each gear design parameter (manufacturing errors). Gea…
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 Elasticity of Shafts, Bearings, Casing and Couplings on the Critical Rotational Speeds of a Gearbox
Emmanuel Rigaud, Jean Sabot
The aim of this study is to analyse the influence of the mechanical characteristics of the set of components on the critical rotational speeds of a gearbox. The case of a gearbox f…
