LubricationBearingsandDetailedPumps

Oil systems can be quickly built from CAD, making GT-SUITE the tool of choice to design, analyze, and optimize lubrication systems and components.  Steady state models can be used to predict pressure, flow rate and temperature distribution throughout the oil circuit.  Transient runs can be performed to predict system priming (filling), resonance and wave dynamics in the system, energy loss in the system over a driving or duty cycle, thermal warm-up, and integration with cooling system models.  Furthermore, oil system components can be studied in detail including pumps with automated model building of vane and gerotor style pumps, bearings with both fast running Mobility and detailed finite element options, cam phasers, and hydraulic lash adjusters.

Product Highlights
