Abstract

Impact performance of side-door impact beam of selected design made of omega cross-section for a sedan car has been presented. Parameters influencing crashworthiness of the component have been used for the comparision of various beam cross-sections .

Five alternative cross-sections, both open and closed, of beams were first compared for their crashworthiness using a model of a simply supported beam impacted by a sphere. Based on this assessment the most promising cross-section was used in the side impact simulation of a sedan. Section made of steel was assessed.

Use of omega cross-section was found to be advantageous as it adequately satisfied the crashworthiness criteria with reduction in amount of intrusion and increase in energy absorption capacity at the front door .
