BODY SECTION ANALYSIS IN BUS ROLLOVER SIMULATION

概要

Bus rollover crashes have claimed many lives and injured even more victims. The rare occurrence of the crash as compared to other crash configurations such as full frontal and side impact has underrepresented the fatality caused in rollover crash. In Malaysia, there have been several fatal high profile cases involving bus rollover. Adopted in 2007, ECE R66 is in force in Malaysia to prevent disastrous consequences as a result of a bus rollover crash. The paper describes the methodology of performing a rollover simulation to a bus, albeit only to selected body section. Commercially available software was used to develop a finite element model based on the manufacturer’s 2D drawing. With close reference to the ECE R66 regulation, simulation was conducted and results were presented in the form of structural deformation overview and energy vs. time history.
