The MOORA method integrated finite element analysis of thin-wall tube structures for energy absorption in the front bumper

Abstract

The developing world economy and the increasing income level cause the number of vehicles on the highways to increase rapidly. The increasing number of vehicles makes the highways more unsafe and increases the probability of accidents. This study is concerned with the dynamic analysis of axial and oblique compression in thin-walled tubes. Tubes under the effect of axial and oblique compression were compared with different cross-section profiles in terms of performance. Collision energy absorbed, crushing force efficiency, peak force, and velocity graphs are discussed in these performance parameters. The collision of the plates is discussed considering the speed and mass parameters that have entered the tubes using different cross-sections. Also, we developed a MOORA model integrated finite element analysis to rank the different alternative structures for different simulation cases. The MOORA model’s ranking results presented the most suitable cross-section profiles that will provide the most appropriate damping result.
