A New Method for Car Body Design Optimization 911074

The object of this study is to present a newly developed optimization method for car body design. In the case of designing car body without roof, lowering of the bending and torsional rigidities which lead to a lowering of resonant frequencies should be considered. In order to overcome these problems, a new optimization method has been developed and applied successfully. This method is based on the pseudo least square method and all the sheet elements in the finite element method are treated as design variables.
