Numerical analysis of aerodynamic lubricated double-decked protuberant foil thrust bearing

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2019
Double-decked protuberant foil bearing is a type of foil bearing that uses two stacking-up layers of protuberant foils as supporting structure. In preliminary experiments, wear failure of foil thrust bearing occurs occasionally due to excessive axial ...

Differentiable and Self-Auditing Transient Dynamics Solver for Ball Bearings: OpenBEARD Cross-Verified Against ADORE

Applied Sciences
A transient multibody dynamics simulation of rolling-element bearings is the basis for the design of high-speed rotating machinery; however, the established solvers are proprietary, cannot be used with automatic differentiation, and offer no built-in ...
