Improving crash-worthiness and occupant safety of bus seat structures in frontal crashes as per AIS023 using Finite Element Analysis

Abstract

Abstract Buses are a popular mode of traveling worldwide. In the incidence of a frontal crash (also called a “Head-on collision”) the passengers seating in the second and further rows gets injured due to sudden impact over the front seats. Any accident can cause injury, but statistics show that head-on crashes are even more likely to result in serious harm or fatality to the driver or passengers in either vehicle. During the frontal crash of a bus, if a passenger collides with the next seat and the seat structure performs rigidly it leads to severe injuries. At the same time the front seat should have enough strength to avoid total collapse of the seat. Thus, to avoid injuries, the seat should absorb impact energy and provide sufficient strength. The present study includes The Finite Element Analysis for bus seat as per the AIS-023 setup with the LS-DYNA explicit tool is carried in the present work. The present results ensure the safety capability of the seat structure in a frontal impact.
