You need a bearing stiffness? Which one? | MESYS AG

28/9/2018· Generally, a stiffness describes the change of a force for a change of displacement. Dividing a force with the displacement c=F/u is only valid for linear systems, instead a gradient or differences should be used, like c=ΔF/Δu for a given operating point. The stiffness of rolling element bearing gets nonlinear because of clearance and because

The influence of the lubricant film on the stiffness and damping characteristics of a deep groove ball bearing - NASA/ADS

This paper experimentally investigates the formation of a lubricant film in a deep groove ball bearing and its effect on the bearing dynamics. A novel test rig is introduced, which allows testing different types and sizes of bearings in real-life conditions. The test rig dynamics are optimised such that the dynamic properties of the bearing are measured in a frequency range …

How are bearing stiffnesses calculated in MASTA? – SMT

2/8/2016· How are bearing stiffnesses calculated in MASTA? Bearing Analysis. For rolling bearings, the stiffness is derived from nonlinear load deflection models using Hertzian contact theory and bearing internal geometry. This calculation is done in 5 dimensions (3 translations and 2 tilts) so the result is a 5×5 stiffness matrix for a particular load.
