Abstract
The risk of injuries and fatalities is severe when bus superstructure fails during rollover accidents. This study deals with two stages of analyses which are superstructure strength having rollover analysis and occupants kinematic analysis. The validation process by correlating the strain results obtained from simple box rollover and simulation process done. The inputs from validation process had been used for full-scale bus superstructure rollover. A complete bus structure was developed and simulation was done according to the United Nation Economic Commission of Europe (UNECE) regulation 66 by utilizing finite element analysis software. Injury to occupant at various locations was studied as well as comparison study between belt occupant and unbelted occupants by using the Mathematical Dynamic Model (MADYMO) software. Analysis suggested that superstructure strength and occupant kinematics consideration can reduce fatality and serious injury in bus rollover accident.
