Tribo-X inside Ansys

PRODUCT DESCRIPTION

Tribo-X inside Ansys – calculation of hydrodynamic journal bearings under variable operating conditions

The load capacity and service life of hydrodynamic journal bearings is determined by the optimal dimensioning of shaft, bearing and bearing housing. With Tribo-X inside Ansys, fast parameter studies can be carried out in minutes, or even seconds, in order to adapt the bearing design to the different applications.

Product Highlights

  • Simple and efficient simulation of the journal bearings with Tribo-X
  • Higher level of detail of the CAD model with realistic visualization
  • User-friendly navigation thanks to simple workflow
  • Determination of own journal bearing coefficients for the rotor dynamics analysis

 

“Linear Rotor Dynamics” add-on module

With this module, the speed-dependent stiffness and damping coefficients of a journal bearing can be precisely calculated.

The vibration behavior of journal bearing rotors is influenced by the stiffness and damping properties of the bearing. The bearing properties depend heavily on the speed and operating load and contribute significantly to stable operation of the rotor. With this module, bearing coefficients can be determined for every operating mode and used for the subsequent rotor dynamics analysis in Ansys.

“Mixed Friction” add-on module

With this module, a hydrodynamic bearing analysis can be carried out, taking into account the surface roughnesses of bearing and shaft.

There is no such thing as “smooth” surfaces in practice. Instead, hydrodynamic journal bearings go through the mixed friction area during start-up and shut-down processes, high loads and low viscosity. In this transition area, the surface roughness of bearing and shaft play an important role. With this module, the roughness is fully taken into account, which allows complete calculation of the Stribeck curve.
