The Challenge
For the past 20 years, ComTec has
been specializing in design, development and testing of highly
complex structures made from fiber reinforced plastics in industries
including aircraft, automotive, sports, marine and piping.
Recently, ComTec was requested to
design a sailing yacht, also known as a trimaran, ensuring a maximum
weight of a 6.5 metric tons (including all additional loads).
Because this yacht was intended for
private use only, the project was very cost and labor intensive.
Furthermore, prototyping was not possible. So ComTec needed an
approach that would enable them to optimize the various structures
of the yacht for the maximum weight quickly and precisely.
The Solution
In order to be able to solve the given task, various features
of COSMOSM were used. ComTec optimized the hybrid skin laminates
of the sandwich construction of the yacht. In doing so, multi-layer
elements were assigned with the relevant orthotropic properties.
With COSMOSM's optimization method,
ComTec was able to detect several weak points, which previously
weren't taken into consideration. Eventually ComTec succeeded
in meeting the requirement of a total weight of 6.5 metric tons
including all additional loads, by using specific reinforcements.
Summary and Metrics:
- Analyzed model with 55000 degrees of freedom
- Utilizing COSMOSM's optimization features, ComTec was able
to detect several weak points which previously had not been
taken into account by sailing experts
- Succeeded in meeting the requirement of a total weight of
6.5 metric tons including all additional loads
