Abstract: The SUPRA SAEINDIA STUDENT FORMULA competitions challenge teams of university undergraduate and graduate students to conceive, design, fabricate, develop and compete with small, formula style, vehicles. The purpose of this paper is to present the steps to follow in order to design honeycomb sandwich structure impact attenuators. Impact attenuator is a deformable, energy absorbing structure located at the front of the vehicle whose sole purpose is to absorb the kinetic energy of the race car and limit the deceleration acting on the human body. Also this paper discusses the crash analysis of the designed attenuator in order to determine the safety of the design. The analysis is done using LS-DYNA whereas the design is carried out using theoretical calculations. Initial requirements were set in accordance with the Supra SAEINDIA Student Formula 2012 rules and they were satisfied with the final configuration crash analysis.
Keywords: Design, crash analysis, Impact attenuator, Honeycomb, Supra SAEINDIA, Student formula.
