The purpose of the roll cage is to provide a minimal three-dimensional space surrounding the driver.Elements of the Roll Cage:Rear Roll Hoop (RRH)Lateral Diagonal Bracing (LDB)Roll Hoop Overhead members (RHO)Front Bracing members (FBM)Lateral Cross member (LC)Lower Frame Side (LFS)Side Impact Member (SIM)Fore/Aft Bracing (FAB)Front Lateral Cross member (FLC)

We have used the rubber & spring damper arrangement in order to absorb shocks due to engine forces on structure in order to have better ride without shocks.We want that minimum engine reciprocating(shaking force = mr2, m=120 g) should be transmitted on our structure, so in order to have ride comfort for that we have proceeded that only 10 % of the force should transmit on our Roll cage. The force transmissibility characteristics shows that in order to have the transmissibility less than one r should be greater than. Since in the second zone of operating characteristics of the machine the value of R 7.0006Dynamic safety factorSD>Sdmin13.571 > 5.0007Bearing pressurepB
