ABSTRACT

For two months, My graduation design is the overall design of the formula racing. we used the contrast analysis method mainly in the design, through optimizing the parameters optimization design and optimization of UG MATLAB, etc.

Initial stage, we according to 2011 auto contest rules determine college equation overall layout of the car, and the demonstration and analysis, the main parameter is determined primarily racing. Through calculation and comparison, sure engine type, primaries drivetrain maximum transmission ratio, minimum transmission.

The intermediate stage, we design UG6.0 3d software used in various parts of assembly for modeling and whole assembly, and suspension, steering movement interference analysis. Use of engine power characteristic curve characteristic, MATLAB software mapped drive car driving forces - resistance balance figure, acceleration curve, and etc, and detailed calculation racing fuel economy.

The final stages UG7.5 are derived by car, general layout, and two-dimensional engineering graphics overall parameter table, and made the first generation and the second generation racing cars are compared and analyzed. For considering the actual production of may change suspension, frame and steering parts, obligate scheme.

Through the graduation design, I understand and master the overall design of car of the steps and method, the professional knowledge of professional knowledge, enhance the data collection and integration of information, these ability after my graduation will be engaged in car design lay a good foundation for the job.

KEY WORDS: FSAE, general parameters, parameter identification, general arrangement,the car power, fuel economy
