Cam Design & Valvetrain Modeling

This course is designed for new users of GT-SUITE Valvetrain Application. It will focus on the simulation of engine valvetrains through the use of VTDesign and GT-SUITE. The following topics will be covered:

• Introductory Concepts of GT-SUITE :
  • 2-D Mechanical Simulation and Visualization
  • Model Setup- initialization, parameters sweeps, Optimization/Design of Experiments
  • Post-processing (GT-POST)
  • Subassemblies and User Compounds
• Cam Design (VTDesign)
  • Develop a profile design starting from an existing a reference profile
• Valvetrain mechanism kinematics, quasi-dynamic analysis (VTDesign)
  • Generate valve lift from cam shape or vice-versa
  • Calculate idealized separation speed  (or Spring Margin)
• Cam Design iteration with interactive feedback on critical design constraints (VTDesign)  Run VTDesign in interactive mode to dynamically generate critical kinematic and QDA calculated design constraints (e.g. min. negative radius of curvature, max. hertz stress, min. oil film thickness, min. separation speed) while modifying the cam design.
• Spring Layout (VTDesign)
• Dynamic modeling of valvetrains
  • Modeling Contacts for Hertz Pressure and Oil Film Calculations
  • Multi-mass Spring Modeling
  • Adding Compliance to Valvetrain Components
• Multi-body and torsional vibration modeling of camshafts and valvetrain systems
  • Adding Valvetrain Branches and Timing
  • Adding Bearings or supports for bending
• Additional Topics (time permitting)
  • Timing Drive simulation (Chain, Belt and Gear)
  • GT-POWER Integration

Notes:
-Computers will be available to use during the training.  Attendees are encouraged to bring USB flash drive to save seminar material.

– Due to the limited room capacity, seats will be allocated preferentially to OEMs and suppliers.
