The deckhouse was too heavy to reach the specified speed.
Task for TGM: Weight reduction of at least 20%.
Two concepts were developed to achieve a weight reduction. The original design was numerically calculated as the basis for the optimizations.
1. topology optimization
- Main load paths were determined with the help of topology optimization.
- From this, a concept with planking sheets and an optimized frame structure was developed.
The weight saving of this concept is approx. 8%.
2. sandwich concept
- An initial dimensioning is carried out analytically, then a concept is created with these results.
- This concept was calculated and optimized in several loops.
- Adoption of the topology-optimized roof structure.
- Reduction and optimization of the individual struts and their wall thicknesses.
- Processing instructions for the sandwich panels have been created.
The weight saving of this concept is: approx. 22%.
