Analytical study on hybrid thrust foil bearing, structural characterization and measurement of static performance 2024, Tribology International Citation Excerpt : The dynamic study results indicated that bearing stiffness and damping coefficients decrease exponentially with initial minimum film thickness. In rece...
By computerizing this model, the displacement of the workpiece and grinding force were simulated with machining time. The simulation predicts the effects of the stiffness and damping coefficients of the spindle bearing on the displacement and grinding force. The effects on the chatter growth rate ...
Hence, stiffness and damping coefficients can provide a good model for a wide range of situations. However, in some cases, this approach does not suffice to describe the dynamic behavior of the rotor-bearing system. Moreover, unstable motion occurs due to precessional orbits in the rotor-...

In Simscape, modelling simple cylindrical journal bearings can be achieved by creating a custom component that represents the bearing. In your case, you have information about bearing reaction forces and clearances for a specific speed of the journal, which is useful for setting up the model.
Findings of this study indicates that the hybrid DLPJB S operating under non-Newtonian lubricant offers enhanced values of \\({\\bar{h}}_{min}\\) , \\({\\bar{\\omega}}_{th}\\) and rotor dynamic coefficients (stiffness and damping coefficients)....
By adjustments to the shape of the pads and bearing clearance, bearing stiffness and damping characteristics can be controlled. This bearing is successful in applications where the pressure-dam design is inadequate. Sign in to download full-size image Fig. 8.58. Top left: Radial bearings; Top ...
A new method to identify the moment and radial stiffness and damping coefficients of isotropic bearings in a spindle-bearing system with incomplete mode shapes is proposed. A complete relationship between the bearing reactions and the incomplete mode shapes is constructed in the form of a system of...
