Overview:

Noise/vibration/harshness (NVH) and fuel economy often must be traded off against each other during the vehicle design process.

Challenge:

When developing a new vehicle model, engineers are responsible for meeting a wide variety of often conflicting performance targets. Fuel economy and NVH are two of the most important categories of targets.

Benefits:
  • This case study successfully demonstrates the FMI integration approach for vehicle lugging NVH assessment
  • Effectively coupled AMESim Converter Controller model with Adams Driveline and Vehicle model
  • An Optimum Torque Converter slip speed was determined meeting lugging target requirement while balancing with fuel economy
  • Simulation results showed drivetrain torsional vibration along with vehicle vibration (steering wheel & seat track) were effectively reduced with converter slip
