Abstract: To meet the requirements of the fast model of bus body structure based on beam elements, a parameterization series-stiffness model is proposed. Taking a typical part of the bus body side as the research object, the accuracy of the shell-solid model is verified be tests. Taking the calculated stress of the shell-solid model as the target stress, the optimum equivalent elastic modulus of the series-stiffness model is obtained by parameter design method. Changing the element size to obtain different optimum equivalent elastic moduli of the series-stiffness model, the relationship curve of element size and the optimum equivalent elastic modulus is established, and the function expression of the curve is determined. Two series-stiffness models of different element sizes are introduced into the whole vehicle model to conduct analysis and comparison. The results demonstrate the feasibility of the proposed parameterization series-stiffness model.

Key words: vehicle engineering, equivalent model, parameter design, bus window, adhesive
