Abstract
In this article, AISI-1020 tubular steel roll cage of a formula one car has been designed and optimized. CATIA software has been employed for designing whereas ANSYS software used for Finite element analysis (FEA). The design of the roll cage has been optimized for maximum load bearing capacity and manoeuvrability conditions. For this purpose, various impact tests have been performed under different conditions in order to determine the level of safety. The effects of different loading conditions on the structural members are studied and discussed. It has been found by the analysis from the front and rear impact tests that less deformation is developed at a higher value of stress. Moreover in case of front rollover and side-impact test, it has been observed that higher stress produces higher deformation. The results show that employed AISI-1020 tubular steel may lead the development of a lighter and safer roll cage design as compared to a conventional Formula-1 roll cage material.
