Integration of topology and shape optimization into the process of the design of mechanical structures elements

Abstract

Rapid development of science and engineering demands of modern mechanical engineers not only the knowledge of classic techniques of mechanical structures design, but also the knowledge of methods and techniques that enable the making of optimal structures or the structures that are close to optimal. This paper presents shape and topology optimization on the example of double-sided hook. Initial shape is a flat plate, having only holes for hanging the hook and the load. At the end of the optimization process, the volume is decreased by 80.92%. The original idea is to perform the whole analysis within one software application - starting from the design of the model, through the preparation of the model for the calculation by finite elements method, calculation and optimization to the analysis of the obtained results. In this case, software CATIA was used. Integrated approach to structural optimization within one CAD software application saves time and money. With this approach, in the early phase of the design, we tend to create mechanical structures elements with optimal characteristics. As the result, we get a real structure, which could be improved further, if necessary.
