The Optimization Of College Student’s Formula One Racing Frame Structure Based On The Finite Analysis

As an important part of the formula one racing car, during the competition, theframe bears full loads from racing track and the weight of all parts and assembly. So thestrength and stiffness play very important roles in the design and working process of theframe. With the finite element analysis of racing car and original frame structure,structural improvements are made to boost the racing car’s comprehensive performance.The cut of design and develop cycle and the reduction of design cost and manufacturingcost has much significance on the light weight.This paper meets the rules and design requirements of the Chinese collegestudent’s formula one racing. Firstly, apply CATIA software platform to set upthree-dimensional model on the first generation of formula one racing car. Combinedwith the finite element analysis, build the formula analysis model of tubular unit onlinewith ANSYS software and simply it. Secondly, through the finite element analysis ofthe frame, the stress distribution and strain situation are obtained under the workingconditions of bending with full load, torsion, braking and rapidly turning. Thenimprovements are made on the places of great stiffness and strength. Finally, apply thefinite element analysis to the new frame again and test the rationality and safety of newframe improvements and the fulfillment of design requirements. Through the FEA,check the stiffness and strength of frame structure and improve the frame structure,optimize the design to meet the frame light weight design.The analytical methods mentioned in the analysis f college student’s formula oneracing car are suitable for the analysis and improvements of other types of frame.
