Journal Bearings

This basic module is used to simulate hydrodynamic journal bearings as they are in motors, pumps, compressors or gearboxes.

Module Highlights

• simulation with time-varying boundary conditions such as load, speed, temperatures, etc.
• laminar und turbulent flow
• arbitrary bearing contour
• consideration of manufacturing and wear profiles
• elastic deformations using FEM flexibility matrices
• lubricant feed via end face, bore, pocket or ring grooves
• bearings with half shells of two different materials
• mixed friction (add-on module MicroSim necessary)
• temperature distribution within fluid and solids
• temperature and pressure dependent lubricant parameters
• non-Newtonian flow behavior with and without limiting shear stress
• wall slip between lubricant and solids
• mass-conserving cavitation
• coated surfaces
• determination of stiffness and damping coefficients
• wear simulation
