Abstract

A study on section property method and section shape method for the optimum design of vehicle body structure M. W, Suh\ J. H, Lee\ K. Y, CW & M.

Abstract In this study, two methods for the optimization of vehicle body structure are proposed for practical application. One is the "section property method" which uses section properties as design variables. This method shows the tendency of an optimum section approximately. The other method is the "section shape method" which utilizes geometric parameters of section as design variables. Practical solutions are obtained by this method. These two methods are compared through several sample problems. The finite element method is used for the structural and sensitivity analyses. 1 Introduction The weight reduction of vehicles aiming at environment preservation and energy conservation is an important subje
