Kurbelwelle TEHD Thermo-Elastohydrodynamic Simulation

Thermo-Elastohydrodynamic
Simulation (TEHD)

The TEHD feature in FIRST takes into account all material-specific properties of the bodies present in the simulation such as specific thermal distortion, heat capacity and heat transition coefficients as well as all temperature-dependant parameters of the lubricating medium and combines them with the EHD simulation.

Highlights of the TEHD module

  • temperature distribution fluid film

  • temperature distribution bodies

  • thermal distortions based on body temperatures

  • viscosity change according to fluid temperature and pressure

  • cooling effects due to oil throughput

  • heat exchange with ambient medium
