AUTO21

• National research initiative supported by the
  Government of Canada.
• Created to enhance the global competitiveness of
  the Canadian automotive industry.
• Over 230 top researchers at over 38 academic
  institutions are involved with AUTO21.

OUR PROJECT

• Sponsored by AUTO21, we are to design a
  two-passenger, drive-by-wire, electric car.
  The car is to be compact and similar to those
  already on the market.
• Seven universities (Queens, Waterloo, Ryerson,
  Western, Dalhousie, Sherbrooke, UOIT) and two
  major companies (General Motors, ABC Group) are
  involved.
• Main objective of the project is to evaluate
  collaboration as it occurs between the teams
  working on different car components. By doing
  so, collaboration tools can be developed and
  improved so future GM projects will run more
  smoothly.

PROBLEM STATEMENT
SUSPENSION DESIGN Our team has chosen to take
responsibility for the suspension system to be
implemented into the car design. The car will be
a compact drive-by-wire electric vehicle and
thus it will require a specialized suspension
design that is compatible with all other
components of the car. Therefore, it is
important that we develop a detailed suspension
design through collaboration with the other teams
working on the project.

EXPECTATIONS

• Determine optimal suspension design.
• Produce a CAD model of suspension mechanisms
  using Unigraphics NX.
• Provide a analysis
• using ANSYS and ADAMS.
• Document our collaboration during
• the design process.

IMPORTANCE OF SUSPENSION

• Improves passenger comfort by absorbing impact
  from bumps in the road.
• Maximizes friction between road
• and tires
• - Improves cornering and handling
  characteristics of the vehicle.
• - Minimizes roll and enhances safety.

PRELIMINARY RESEARCH
MACPHERSON STRUT

• Most common type of suspension in front wheel
  drive cars.
• Compact and light with good handling and ride
  characteristics.

PRELIMINARY RESEARCH
DOUBLE WISHBONE

• Very common type of front
• independent suspension
• system.
• Minimizes roll or sway
• for better steering feel.
• Larger and heavier than the Macpherson strut.

DESIGN TOOLS

• Throughout the design process we will use the
  following tools
• Morphological Chart
• QFD
• FMEA

• Will optimize design and also increase the
  design
• stage efficiency.

COLLABORATION TOOLS

• TWiki and TCC (Team Centre Community)
• Interactive websites that allow for organized
  discussions and uploading of ongoing work among
  all group members.
• Excellent way to communicate
• ideas and designs with group
• members from other universities.
