This paper deals with development of a computer simulation procedure, as a substitute for physical rollover test, to evaluate bus body structure crashworthiness. It is expected that, when completed, this procedure can be proposed to the authority to enhance its current type approval procedure related to crashworthiness which is merely based on qualitative and empirical field experiences without performing real rollover test. This procedure will enable afirmer base for judging the crashworthiness of bus structure. The proposed computer simulation procedure is being developed based on ECE R66 which allows partial bus body structure to be physically tested. In this case, sections of bus super structure built up from at least two bays are used to represent the whole structure. A finite element method computer program capable of dealing with elastic plastic calculation is employed to calculate deflection of a bay structure under incremental quasi-static loading until residual space limit is reached. From the obtained force-deflection curve, the strain energy absorption capacity of the structure will be evaluated if it is large enough to absorb potential energy resulting from rollover test. A bus body superstructure sample from a representative domestic bus manufacturer is used as test cases.
