Chatter avoidance in the milling of thin floors with bull-nose end mills: Model and stability diagrams
(Elsevier, 2011-01)
The milling of thin parts is a high added value operation where the machinist has to face the chatter problem. The study of the stability of these operations is a complex task due to the changing modal parameters as the ...
Efficient assembly of bolted joints under external loads using numerical FEM
(Elsevier, 2018-05-16)
Several factors can cause leakages in a bolted flange connection, external loads being the
most important one. External loads such as those produced by misalignment introduce an
external axial load combined with a bending ...
Load distribution and friction torque in four-point contact slewing bearings considering manufacturing errors and ring flexibility
(Elsevier, 2019-03-16)
This work introduces a methodology for the calculation of the load distribution in four-point contact slewing bearings
considering ball preload, manufacturing errors and ring flexibility. The model is built by the formulation ...
Friction torque in four contact point slewing bearings: Effect of manufacturing errors and ring stiffness
(Elsevier, 2017-02-24)
This work outlines a procedure for the determination of the interferences between balls and raceways in four contact
point slewing bearings due to manufacturing errors. The procedure is applied to a particular case and ...
Friction torque in four-point contact slewing bearings: applicability and limitations of current analytical formulations
(Elsevier, 2017-11)
The friction torque is a key parameter in the design of slewing bearings. The most challenging issue in its calculation
resides in the modelling of rolling element contact mechanics. In this manuscript two models for the ...
An engineering approach for the estimation of slewing bearing stiffness in Wind Turbine Generators
(Wiley, 2018-11-30)
The stiffness of yaw and pitch slewing bearings has a critical influence on the structural
behaviour of Wind Turbine Generators. Thus, it is commonly required by designers for
their simulations to estimate deformations ...
Static structural behaviour of wire bearings: comparison with conventional bearings and study of design and operational parameters
(Elsevier, 2018-10-28)
In wire bearings the rolling process occurs on raceways machined on steel wires, and the rings are
made of light materials such as aluminium. This particular architecture provides both weight and
inertia savings, but ...
