DESIGN OF STEERING SYSTEM OF SELU MINI BAJA

DESIGN OF STEERING SYSTEM OF SELU MINI BAJA CAR Benjamin Genre Advisor: Dr. Ho-Hoon Lee

Design Goal ■ To create a C-Program capable of determining the steering error of a Mini Baja car. Mini Baja Car

Importance of Steering Design § Plays important role in car’s maneuverability. § Reduces skidding and wear of tires.

Resources of Design ■ Paper already previously written by Alfred Showers, Ho-Hoon Lee, and Cris Koutsougeras. ■ Determined use of commercially available rack and pinion system and steering knuckle assembly. ■ Use of Ackermann principle of steering design. ■ Computation of steering error. Rack and Pinion steering system

Rack and Pinion ■ Composed of two gears. ■ Use of rotational motion to create linear motion. ■ Most common type of system. Rack and Pinion steering system

Ackermann Steering Principle § States the geometric arrangement of all the axial lines in the steering of a car should meet at a point.

Steering Error § Steering error will be inevitable. § Goal is to minimize error by finding ideal distance from the front axle to the steering rack axis.

Creating a Steering Error Program § Frame dimensions not yet determined. § Use of program such as Visual Studios. § User will only have to input the specific parameters of a vehicle to be give the steering error. § Will help in determining best commercially available steering system to be used.

Deliverables Dates Deliverables February 24 th-March 10 th Study research paper and begin outlining program March 11 th – March 31 st Begin writing program. April 1 st-April 14 st Test program with frame design teams current design and measurements April 15 nd – April 23 th Research possible steering assemblies and estimate cost. April 23 rd – May 3 rd -Finalize program and calculate optimal distance from the front axle to the steering rack axis for both frame designs. -Determine the best commercially available steering systems to be used.
