Abstract

The use of generative design as an alternative to typical structural optimization techniques opens the door to new methods of manufacturing. In this study, generative design techniques were used as an automated iterative process with an extensive set of control variables and initial models to explore and optimise the stiffness and weight of different configurations for a 3 MW offshore wind turbine electrical generator structure. With this new approach of adding generative design techniques to a structural optimization process, a 4% reduction in structural mass was achieved. The modification in the structural geometry also help to enlarge the machine's operational range with the consequent growth in energy gathering.
