This course is intended for new and existing GT-SUITE users interested in developing detailed transmission and driveline models. The focus of the course will be modeling the internals of the transmission, including the rotational and axial mechanics and the clutch actuation systems. Coupling the detailed transmission model to an engine and vehicle model will also be accomplished to evaluate shift quality.

Introductory Concepts of GT-SUITE :

  • 1-D hydraulic control systems for actuators (control valves and pressure regulating valves)
  • Model-building from CAD data
  • 1-D torsional driveline modeling
  • Wet clutch models
  • Integration with Simulink

The class will include discussion of detailed, predictive component models in which the fluid-mechanical interaction is important.  Most of the instruction will be based on interactive model building, but may also include demonstrations from the instructor and guided examination/analysis of pre-built models.  Below is a list of common topics that can be prioritized based on the audience.


The following modeling topics may be included:

  • System-Level Transmission Modeling
    • Shift Strategy Generation
  • Torsional vibration analysis
    • Time and frequency domain
    • Integration of GT-POWER engine model
    • Torsional damper modeling
  • Real Time Modeling
    • Model preparation and reduction for HiL applications
    • Supported platforms
  • General GT-SUITE topics
    • Fluid properties
    • Cavitation and aeration
    • Optimization and DOEs
    • Others

Note:  This course may be offered as a future open registration event OR requested as a custom training at a GTI office location or your location.
