A Study on Design and Crash Analysis of Automotive Energy Absorption Tubes

Abstract

In engineering and technology safety of human life has always been a top priority. With the increasing usage of vehicles in everyday life, probability of deaths and injuries has also increased, but safety is important too. The main aim of this study is for designing an energy absorption tubes (Crush Can) of different shapes, thickness, at 10 km/hr speed and checking its performance by numerical simulation on the basis of FMVSS by using Finite Element Analysis and evaluate the result by changing design of Crush Can in the form of stress, energy graphs are plotted, by comparison of results, we can suggest that 1mm thickness and circular design absorb optimum stress and more energy than other. The HYPERMESH software is used in meshing and LS-DYNA software is used as a solver
