Details about the software products
The behavior of shafts with journal bearings very much depends on the static and dynamic properties of the lubricating film in the journal bearings. Elastohydrodynamics (EHD) has established itself for the simulation of lubricating film formation.
With Tribo-X inside ANSYS, you can conveniently and efficiently carry out the computation of hydrodynamic journal bearings in ANSYS Mechanical. The objective is to correctly dimension the bearings as well as realistically map the rotational speed-dependent stiffnesses and dampings in dynamic FEM analyses.
Areas of application:
- Coupling of hydrodynamics and FEM
- Determination of journal bearing coefficients (stiffness and damping coefficients) for the following rotor dynamics analyses
- Bearing deformations
- Mixed friction
- Cavitation and bearing capacity
- Parameter studies
- Complete integration of journal bearing computation with Tribo-X in ANSYS Workbench
- Short computation times despite high degree of detail
- Inclusion of elastic bearing deformations and their effects on gap geometry
- Complete mapping of the Stribeck curve through the inclusion of mixed friction
- Identification of rotational speed- and load-dependent bearing coefficients
- Fully parametric workflow
Tribo-X inside ANSYS – Radial Bearing EHD
- Simulation of the hydrodynamic or elastohydrodynamic behavior of radial journal bearings
Tribo-X inside ANSYS – Linear Rotordynamics
- Extension to determine rotational speed-dependent linear stiffness and damping coefficients for the following rotor dynamics analyses (additionally required: Tribo-X inside ANSYS – Journal Bearing EHD)
Tribo-X inside ANSYS – Mixed Lubrication
- Extension to include mixed friction states (additionally required: Tribo-X inside ANSYS – Radial Bearing EHD)
