Snapshot Presentation for:

Why H-FSAE?

NIATT seeks to be a leader in “Green Vehicle” technologies

Hybrid Technologies can improve performance as well as efficiency

The Hybrid FSAE competition will provide experience to young engineers in this emerging field

The Hybrid FSAE competition provides an engaging project for students to participate in

Conclusion of how to design a Hybrid FSAE car:

Single motor evaluation Behavior of dual input to power differential

Evaluation and selection of hybrid solution to implement

Evaluation of actual engine to be used

Previous U of I FSAE competition knowledge

Development of electronic power-management system

Including component selection

Frame development and packaging team that accommodates

new components

Suspension / Brakes / Final design

COMPETITION

Miniature Hybrid Test Platform:

Phase 1 : Completion of the Dynamometer The Water-brake dyno was reverse engineered by last years ME 301

class (of which three of our team members were in)

It was built in our machine shop by students under the direction (and with substantial personal investment) of Russ Porter

Our team had to install seals, check bearing speeds, specify a force transducer, determine how to monitor RPM, and develop the data acquisition strategy

Phase 2: Modifications to Planetary Differential

Phase 3: Single Motor Testing Evaluate the motor characteristics to determine if selected

brushless DC motor is right for competition. Provide an intermediary step to completion:

○ 1. Allows parallel paths for data aquisition and full build○ 2. Tests most major components so that problems can be

identified early-on.

RIPThese motor controllers gave their life so

that the H-FSAE team could know more. May they rest in peace.

Phase 4: Dual Input Prep

Allows future teams to develop a comprehensive control strategy for the racecar on a smaller model (less expensive mistakes)

Demonstrates the interaction of two-power sources to the planetary drive.

Will serve as a learning platform for future teams to get up to speed on the advantages of the planetary drive.

Is a great demonstration piece for the U of I

Future Work Completion of the test platform so that more

reliable data can be collected. This includes:○ Using faster data processing to be able to measure

high motor speeds.○ Finalizing Data Acquisition and making the test stand

more user-friendly. Development of a control system and simulation of

road loading Engine characteristics of the YZ 250F PUTTING IT ALL TOGETHER for competition!!!
