AN EXPERIMENTAL STUDY ON CAR SAFETY THROUGH ROLL CAGE SPRING, BUMPER

It is important to know their mechanical properties and their failure mechanism during the impact in order to increased the safety of any vehicle. This thesis focuses on the design of bumper, spring and roll cage for lesser weight and better performance. Also it describes about the stress analysis on a car frontal protection system (bumper) simulations. Research concentrates on composite material. It is considering their function, geometry, and other parameters that influence the compatibility of the bumper and roller cage In future research, these parts will face the static test and analysis will be done on their load distributions by applying the variation of load and locations. We analyze the basic concepts for improving the safety on the car by doing analysis on the car bumper and roller cage.. This analysis was carried out by using ANSYS for structural physics that could simulate static (stationary), dynamic (moving) and thermal (heat transfer ) problems to evaluate the behaviour of bumper system and roller cage. Another additional innovative step for improving crashworthiness is the use of material to produces the part to absorb energy during the process of a crash and that part is spring. Here we will use spring on the front side of the vehicle to absorb the energy of sudden impact and this will secure the driver as well as produce less injury to the person outside. How the load applied effect the stress distribution.
