Design, Fabrication and Testing of Impact Attenuator for Student Formula Car

Abstract

The impact attenuator is a vitality safety gadget introduced forward of the front bulkhead of the vehicle with the capacity to absorb impact force and to shield the driver from a sudden difference in energy experienced due to sudden shock on occasion of an impact. This is accomplished by disfiguring plastically and engrossing a piece of the all-out vitality required amid a crash. The point of this undertaking is to give advancement toward the standard and customary attenuators for equation understudy vehicles and testing its viability with accident test examination. The primary part of this undertaking is arranged to get ideal estimations of active vitality advancement amid the frontal contact with the most reduced beginning deceleration. In the present work, design and fabrication of low-cost, lightweight impact attenuator were carried out. And also, compression tests were carried out on impact attenuator to study deceleration and impact behavior of attenuator. Based on the experimental results, it was found that impact attenuator with beverage tins and polyurethane foam satisfies all functional requirements and design rules set up by Formula SAE. This attenuator provides better energy dissipation. Miscellaneous advantages of the same impact attenuator are reduced weight, low cost and easy fabrication.
