Reducing weight while maintaining performance is one of the key challenges facing the automotive industry. A new study, titled Enhancing engine mount design through topology optimization for additive manufacturing, highlights how advanced digital engineering and additive manufacturing technologies can help address this challenge by rethinking the way mechanical components are designed and produced.
The research, conducted by the Hellenic Mediterranean University (HMU) and the Technical University of Crete (TUC) within the CRETE VALLEY framework, focused on an automotive engine mount bracket, a critical component that supports the engine and helps absorb vibrations during operation. Using a combination of 3D scanning, finite element analysis, and topology optimization, researchers created and evaluated alternative design solutions that could deliver the same structural function with less material.
The topology-optimized design achieved a significant reduction in weight, cutting the component’s mass by approximately 30% while maintaining nearly the same level of overall displacement under load. The study also investigated two innovative lattice-based geometries, known as gyroid and auxetic structures, which are increasingly attracting attention for their unique mechanical properties and compatibility with additive manufacturing.
While the gyroid and auxetic configurations offered specific advantages in terms of stress distribution, they also showed different deformation behaviours compared with the topology-optimized model. These findings underline the importance of selecting the most suitable design strategy depending on the performance requirements of the final application.
More broadly, the study demonstrates how the combination of topology optimization and additive manufacturing is opening new possibilities for the development of lighter, more efficient and more sustainable products. By enabling complex geometries that are impossible to manufacture using conventional methods, these technologies are helping engineers push the boundaries of innovation in the automotive sector and beyond.
