Comparative design and analysis of roll cage for automobiles

Abstract

This paper deals with the comparative analysis of the roll cage for the performance automobile. In a performance automobile, the roll cage is one of the main components. It forms the structure which provides additional protection and prevents the vehicle from crumbling. It must be of adequate strength to protect the driver in the event of a rollover or impact. There are different organizations across the globe which provides car manufacturer a certificate of crash worthiness and structural strength of the cars during the collision. Conducting the car crash test will take much time and cost so in order to solve these problems and Improvise the design of the Body in White part of the car (BIW) a finite element model of the car is developed and it is tested virtually over and over to ensure that the passengers are safe inside the car during an impact. The main thing about the simulation is the cost effectiveness and can be done in lesser amount of time than testing the actual model. Mainly there are three modes of crash testing which are performed in Insurance institute of Highway Safety such are Frontal Impact test, Side way Impact test and Roll over test. Here a BIW part of the car is taken along with the roll cage designed by us with carbon fiber (ePA-CF) material properties and ASTM A36 steel properties (comparison) for the dynamic analysis using ANSYS workbench and LS DYNA.
