- This paper describes further investigations that have been carried out to make the proposed procedure [5] becomes more reliable to be practically applied as a requirement in bus type approval. One important aspect highlighted in this paper is an effort to improve the accuracy of the FEA model by taking into account detailed construction of bus superstructure. It worth to note that, based on survey carried out on several bus manufacturers, the detailed construction may vary from manufacturer to manufacturer. As a case study, a bus superstructure from a prominent manufacturer was chosen as a sample. Energy absorbing capacity of a bus superstructure section consisting of four bays including rear entrance door, emergency door and rear end was investigated through elastic-plastic finite element model. Incremental quasy static load according to ECE R66 was applied, subsequently to the right and left cantrail to obtain load deflection curve. Then the energy absorbing capacity of the structure when residual space limit was reached was evaluated through derived energy deflection curve. Essential components of the bus superstructure governing its energy absorbing capacity will be discussed. Modeling strategy in dealing with elastic-plastic analysis for such a rather complex structure is also highlighted.
