66th General Assembly of the International-Academy-for-Production-Engineering (CIRP), Guimaraes, PORTUGAL, AUG 21-27, 2016International audienceThis article presents new tools developed to improve the geometrical corrections required on roller bearings of Helicopter gearboxes suffering from heavy deflection. A complex non-linear finite element model of the whole gearbox is firstly implemented to identify the deflection of inner and outer raceways under operational loads. The computed misalignment is then used as an input to predict and check the contact pressure edge effects occurring in the contact area and iteratively optimize the roller shape. Several approaches are tested based either on Boussinesq's potential theory or on specific FEM calculations. They permit increasing the service life of the bearings while reducing the overall gearbox development lead-time. (C) 2016 CIRP

“…With the aim of improving contact pressure distribution several approaches have been investigated. Among them, we can find developments in material properties [21][22][23], on topology [24][25][26], on surface texture [27][28][29] and on shape [30][31][32][33][34][35]. These works are based on optimisation algorithms following either gradient-based or heuristic strategies.…”

A framework for assessing the capacity of railway axle journal bearings is presented after elaborating on the locale rolling contact fatigue (RCF) failure mechanism. Three phases are conducted, including the determination of bearing service loads, finite element analysis (FEA) on the localized RCF stresses of bearing components, and the life-related capacity assessment on the bearings and bearing components. Results prove that wheel-track (WT) contact forces inspected by an instrumented wheel set can be transferred into bearing service loads. Two-step FEA from the global wheel set to the local bearings is used to obtain localized RCF stresses at dangerous locations around the bearing contact regions. After determining the locations, a life-related capacity assessment is performed by evaluating equivalent RCF stresses and lives at the locations to determine the weakest bearing component. Typical practice is given in agreement with FEA. This method deals with the FEA of bearing structures, material cyclic stress-strain curves, and probabilistic RCF life curves. Therefore, this work greatly enhances the development of rail-bearing materials, innovative structures, and capacity assessment.
