Applying Generative Design for Development of Optimal Parts

Abstract

In recent years generative design and topology optimisation have been added to CAD. Tools like generative design will generate an optimal design given a model that captures the part intent. Depending on the model criteria, optimal designs may be lighter, stronger and cheaper than parts developed through conventional means. Such benefits are of great interest and companies may want to introduce such tools into their development process. In this project, a diverse selection of Volvo Penta parts is investigated using the generative design tool newly introduced to their CAD system. By reverse engineering the parts and understanding the system and requirements, a model describing the structure and volume of the part was created. Using this model several alternate parts were generated and evaluated using a cost model describing the cost of manufacturing and cost during operation. The parts generated through generative design were shown to be superior compared to the original with the performance indicator used. Drawbacks were also shown mostly relating to implementation and difficulties in defining the models.
