Parameters of Side Intrusion Beam Affecting on Crash Force Efficiency During Impact

Abstract

Occupants safety is one of the most important criteria in car design. Due to the less space between occupant and side door, the scope of energy absorption is less. Hence in a case of side impact, the strength of side door is plays crucial role. A side intrusion beam is mount inside the side door and is also called side impact beam. During side impact, side intrusion beam gets deformed and it absorb the highest amount of energy compare to others parts of side door. And also for smooth bending during the impact, nearly equal amount of force should absorb during the whole bending process. So design of side intrusion beam is important part of vehicle door design. The various parameters of intrusion beam like, material of intrusion beam, shape of intrusion beam, dimensions, mounting of beam inside the door etc. are affected on the strength of side door. In present work using finite elements analysis the effect of important parameters of hollow circular cross section side intrusion beam on Crash Force Efficiency (CFE) is studied. The ABAQUS software is used to perform various finite element simulation. In the first part of this work most influential parameter is determine by Design of Experiments and ANOVA analysis, in a second part of this work relative effect of this influential parameter on crashworthiness of side intrusion beam is studied.
