Abstract
The automobile energy-absorbing component equipped at the front end of car, is one of the most important automotive parts for crash energy absorption .The C- Chanel with two main longitudinal members will absorb most of the crash energy with a progressive folding deformation of a steel column. The longitudinal fail under progressive folding pattern which absorb shock energy. A rectangular tube with C- Chanel (Bumper System) of mild steel is analysed for its energy absorption capability using the finite element based software LS-DYNA. For preprocessing & post processing, software HYPERWORKS is used. Meshing is done using Belytschko Tsay shell element with 5 mm element size. Quasistatic Analysis are carried out in this work for axial loading. Mean crushing load is taken as a parameter for validation of the results. The analytical equations of square tubes are used for comparison of mean force. Energy absorption, Peak crushing force and deformation of the Bumper System are observed during the analysis
