SBFEM with reduced modal basis for hydrodynamic bearings
Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 2, October 2023., 2023 Abstract The numerical effort of transient rotordynamic simulations is often dominated by the computation of nonlinear hydrodynamic bearing forces. These forces are described by the Reynolds equation and need to be computed at every time step. Usually, numerical models, analytical approximations, or look‐up table techniques are employed, depending on ...
