Sammanfattning
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.
