University of Michigan Car [2]

Chassis and SuspensionDesign Objectives

Chassis weighing under 50 poundsTorsional Rigidity greater than 2000 lbf/degMinimum wheelbase of 60 inchesDesign for ease of maintenance

University of Pittsburgh Chassis [4]

Chassis and SuspensionDesign and Analysis Plan

Comply with all FSAE rules and regulationsUtilize Ansys to analyze stressesUse strong and lightweight materialsSuspension requires two inches of travel

Driver Interface Sub-Team

Wilwood Steering Rack [6]

Driver Interface Overview

Create a design where the driver is in full control and completely aware of how the vehicle is running.

Goals: 1. Give the driver a display of the engine

vitals without being cluttered2. Create a system as light as possible3. Keep total costs as low as possible4. Keep driver comfortable and in control

Driver InterfaceDesign Objectives

This means:Keeping our design simple is a mustGiving the driver room to perform all the tasks of racing the carGiving the driver as much control as possible while keeping the cost at a minimum

Pedal Assembly [6]

Our overall objective is to give the driver comfort and simplicity of controlling the vehicle.

Driver InterfaceDesign and Analysis Plan

Research the designs of the top teamsResearch the pros and cons of different partsDecide what parts to useSet everything up to provide utmost comfort and control

Drivetrain Sub-Team

Gear Assemblies [7]

DrivetrainDesign Objectives

Design drive train (computer aided drafting, finite element analysis)Manufacture drive-train components (CNC machining, mill, lathe)Optimize power and fuel economy through engine modificationsMinimize drive-train weight by utilizing chain drive instead of a geared differential

Transmission Assembly [7]

DrivetrainStage 1: Engine Modification Options

Turbocharger increases air flow into engine, creating more power

Garrett GT-12 Turbocharger [8]

DrivetrainStage 1: Engine Management

The Power Commander is a fuel injection adjustment unit that plugs "inline" with the bike's stock ECU (Electric Control Unit).Controls fuel mapping, ignition timing and other engine parameters Power Commander [10]

DrivetrainStage 2: Engine Modification Options

Degree the cams Mill the head Smaller head gasket Weight off the flywheel Weight off the crank Tune air-fuel mixture

High Compression Piston [9]

DrivetrainTransmission

Utilize a chain driven transmissionAll engines are already configured for a chain driven systemAllows for easy gear ratio changeMachine center hub to fit common bike sprocket bolt pattern
