ROLL CAGE DESIGN AND ANALYSIS FOR FORMULA STUDENT RACE CAR

This paper deals with the Design and Analysis of Roll Cage for the Formula Student Car. In a Formula Student Car the roll cage is one of the main components. It form the structure or the main frame of the vehicle on which other parts like Engine, Steering, and Transmission are mounted. Roll Cage comes under the sprung mass of the Vehicle. There are a lot of forces acting on vehicle in the running condition. These forces are responsible for causing crack initiation and deformation in th e vehicle. Deformation results in Stress Generation in the Roll Cage. Hence it is important to find out these areas of maximum Stresses. In this paper an attempt is made to find out these areas by carrying out FEA of the Roll Cage. We have carried out Cras h Analysis (Front and Side Impact), Torsional Analysis, Bump Analysis, and Modal Analysis. In running condition, there are vibrations generated in the vehicle. Here in this paper the Vibration analysis is also done known as Direct Frequency Response Analys is. All these Analysis have been carried out in HyperWorks 13.0. The design procedure follows all the rules laid down by FSAE Rule Book for Formula Type Cars.
