Course Learning Outcomes

This course provides senior undergraduate and graduate mechanical engineering students with an introduction to ground vehicle technologies and automotive engineering, with a focus on dynamic response and handling. Students completing the course will understand the basic layout of modern vehicles in terms of structure and critical functional subsystems, as well as the loads acting on a vehicle during various operational modes. They will able to write the system equations of motion and solve them to determine the vehicle dynamic response. Modern CAE software is used for vehicle performance optimization. The course concludes with an overview of emerging trends and technologies.

  2. Vehicle classification and architecture, weight distribution (3 classes)
  3. Drive train characterization (2 classes)
  4. Drive train kinetics: traction, squat/pitch and roll (3 classes)
  5. Brake systems: system components and operational characteristics (2 classes)
  6. Brake systems: proportioning, stability, anti-skid and traction control features (1 class)
  7. Aerodynamics (3 classes)
  8. Rolling resistance and tire models (2 classes)
  9. Vehicle ride: dynamic models, excitation sources, active response control (4 classes)
  10. Turning behavior: geometry and kinematics, understeer, suspension influences (4 classes)
  11. Steering systems: typical configurations, components, and design considerations (4 classes)
  12. Suspension systems: typical configurations, components, design considerations (3 classes)

  3. Aerodynamic drag assessment using SolidWorks Flow Simulation CFD package.

Class/Laboratory Schedule

Three 50 minute sessions per week devoted to lecture, discussion, and design/analysis problem solving.

Evaluation

Homework assignments (5) - 15%, individual design projects (2) - 15%, midterm exams (2) - 30%, team design project - 25%, final exam - 15%. Graduate students are required to write more extensive reports for the individual design projects, with a format consistent with a technical journal submission, external references, and a minimum length 50 percent greater than required for undergraduate students.

Curriculum Criterion Contribution

Engineering design: 1 credit, engineering science, 2 credits.
