ODU Formula SAE MAE 435 Midterm Report
Formula SAE • The Formula SAE competition challenges teams of university undergraduate and graduate students to conceive, design, fabricate, develop and compete with small, formula style, vehicles.
Competition • Dynamic Event Points: • Acceleration (75) • Skid-Pad (50) • Autocross (150) • Efficiency (100) • Endurance (300) • Static Event Points: • Presentation (75) • Engineering Design (150) • Cost Analysis (100)
Our Team • MATTHEW SANTJER • BJORN MALMFELDT • CHRIS SAVEDGE • MICHAEL TERLESKY • ROBERT SLADE • RICHARD JONAS • GEORGE KOUTROS • JASON LENHARDT • JOHN PRESGRAVES • DANIEL SMITH • RYAN TETER • NICHOLAS GARNER
Suspension • Suspension has been designed in SolidWorks. • Suspension Geometry was identified using Optimum Kinematics.
Suspension • Shocks, pushrods, and rockers have been installed • Camber, caster, and toe has been properly set • The rockers were designed for ideal motion ratio and linear spring rate
Differential Analysis • The differential has been designed and fabricated. • SolidWorks analysis will be conducted on the existing design.
Intake • The intake has been fabricated and installed. • Currently we are analyzing different restrictors designs in SolidWorks • The team will 3D print several restrictors and test on the flow bench.
Exhaust • The headers has been installed on the engine and leak tested. • The firewall is being designed to insure the seat and fuel tank are not subject to heat produced by exhaust system.
Aerodynamics • Body panels are being fabricated using fiberglass. • Analysis will be conducted with Fluent software to calculate maximum downforce generated by diffuser.
Brakes • The calipers have been mounted to the uprights. • The pedals have been fabricated & installed and master cylinders mounted on the frame. • Hydraulic pressure has been adjusted and a thermal analysis is being conducted on the system.
Control System • The manual shifting lever has been fabricated and installed on the car. • Force analysis for the pneumatic shifting system has been conducted. • MXL Strada is awaiting purchase and will be electrically mated with ECU upon arrival.
Pedal Assembly • The pedal setup is a three pedal assembly with a clutch, brake, gas arrangement. • Analysis has been conducted on each pedal using SolidWorks
Progress - Chassis Design • The chassis design and fabrication has been completed. • Our team started by fabricated the current table to be level in all planes and mounting holding brackets for the front, console, driver, and rear hoops. • The structural members have been fabricated using hollow 4130 steel using the following types: • 1”x1”x0.049” Square • 1”x0.095” Round • 1”x0.065” Round • 1”x0.049” Round
Progress - Parts • Metal Concepts Inc. has fabricated parts for the pedals, differential, intake, and suspension.
Progress - Steering • The steering rack has been aligned in plane with uprights for smooth wheel movement. • The steering rods have been fabricated and connected to the steering knuckles on the uprights. • The steering wheel has been located and mounted for best possible driver ergonomics.
Progress - Uprights • The uprights have been designed, fabricated and installed. The upper and lower A-Arms and steering have been connected and tested.
