Topology Optimization of a Ship Gearbox Housing for Catamarans
Arnulf Deschler, ZF Friedrichshafen
Topology optimization has become an integral part of the
modern development process. Components are designed and built
as proposed by the optimization programs. Optimum design,
however, is not guaranteed merely by employing the various
optimization programs. Interpretation of the results is of
crucial importance. In some cases, drafts of the component
to be optimized already exist before optimization starts.
Comparing these drafts with the optimized component can only
reveal the measure of improvement attained. The question,
however, as to what extent the optimum has been achieved remains
unanswered.
This paper briefly presents the installation situation and
the load the transmission is exposed to. The procedure for
optimizing the housing is explained and the results as well
as their interpretation and implementation by means of a produceable
structure are shown.
Subsequently, an approach is presented as to how the quality
of an optimized design can be analyzed with regard to the
optimization potential utilized. This approach is demonstrated
by means of the transmission housing.
