  1. Current Trends in Vehicle Driveline Modeling and Simulation Richard Jacobson Dan Kedziorek

  2. Driveline analysis is an important part of the vehicle design process The tool for driveline analysis depends on the application Several driveline analysis programs will be discussed with various levels of compelxity Make comparisons and help select the right tool Introduction

  3. Description of a Vehicle Driveline Reasons for Driveline Simulation Descriptions of Selected Simulations Conclusions Topics

  4. Description of a Vehicle Driveline ADVISOR2002 Driveline Diagram

  5. Evaluate Vehicle Performance Top Speed, Acceleration, Fuel consumption, Cross-Country Speed (truck/SUV), Shifting, Emissions, Handling, Vibration Evaluate Vehicle Mobility Top Speed, Acceleration, Fuel consumption, Cross-Country Speed, Shifting, Emissions, Speed on Slopes, Obstacle Crossing Reasons for Driveline Simulation

  6. Propulsion System Performance Simulation (TARDEC in-house program) System for Computer Aided ANalysis (SCAAN) from Allison Transmission ADVISOR2002 National Renewable Energy Lab (NREL) Ricardo Libraries for MSC Easy5 from RICARDO GT-SUITE from Gamma Technologies Powertrain Control Research Laboratory (PRCL) University of Wisconsin-Madison Several simulations

  7. Developed at TARDEC Low Resolution Limited performance analysis Acceleration slope performance fuel consumption Propulsion System Performance Simulation

  8. High resolution Extensive input and output Graphical User Interface Customizable (built on MatLab) Detailed output ADVISOR2002

  9. ADVISOR2002 Example

  10. Many pre-built components Graphical User Interface Takes some work to learn Customizable (can link to MatLab) Extensive outputs Easy5 Ricardo Libraries

  11. RICARDO Libraries for Easy5 Example

  12. A service provided by Allison Transmission Low resolution Limited Performance Analysis Acceleration Slope performance System for Computer Aided ANalysis SCAAN

  13. Custom build simulations Has provided driveline simulations to the Army for the following: HMMWV M916/M870 M1A1 M2A2 Powertrain Control Research Laboratory

  14. High resolution Highly detailed engine characteristics Graphical User Interface Can be coupled with CFD code and SIMULINK User code can be incorporated Gamma Technologies GT-SUITE

  15. Different levels of fidelity Different things simulated What does it all mean There are many different tools Can help speed development of advanced drivelines Future Work Increase use of Easy5 Ricardo Libraries Advance the state of driveline simulation at TARDEC Conclusions
