Displays the purpose and characteristics of bus body structural optimization in its conceptual development and presents the method of establishing a simplified parametric finite element (FE) model for concept structure analysis. For application of this optimization and simplified parametric FE model, a case study of structural optimization for bus conceptual design, which is for increasing the whole torsion rigidity and reducing the weight of skeleton of body, has been conducted. The optimizing results are most important for conceptual evaluation and detail structure design.
