Title The Improved Design of the Braking System of FSAE Racing Car
Formula SAE race was founded in 1979 by the Society of Automotive Engineers， more than 600 teams participate in various races around the world every year. From 2011, China started to hold the first match for Chinese college students, this will be designed according to the rule for the match in China.
This paper mainly introduces the improved design of braking system of the Formula Student. First of all, the meaning of breaking system and its development is introduced, and a brief introduction of the braking part of the rule is given right after it. After analyzing the structures of the braking system, it is planned to use hydroid double-circuit brake system with front disc and rear disc. Then, according to the relevant parameters of the racing car, the process of the calculating and designing of the braking system is provided in it. By analyzing the propotional relationship of the front and rear braking force, the distribution line of the braking force is figured out. At last, the three-dimensional solid models of the main components are established by CATIA, parts and assmeblies are drawn with AutoCAD.
Keywords braking system, design, braking disc
