HyperWorks in the Analysis and Optimization of Composite
Structures
Markus Longeru, Sogeti
The presentation Hyperworks in the Analysis and Optimization
of Composite Structures‘ provides an overview of the
use of ALTAIR software applications in engineering
supplier tasks.
The presentation shows the main fields of activities,
where ALTAIR products lead to advantages
by means of calculation quality and project
performance. On the
exemplary projects,
that have been performed by SOGETI HighTech,
such as meshing an AIRBUS wing cover, calculate
vibration and shock of a ship
antenna, optimizing military antenna structures
made of GFRP and secondary aircraft structure
made of CFRP the application
for various industries with their specific
problems and solutions will be shown.
For the wing cover, a detailed FE model of
shell elements is generated, which needed
a high grade of automation due to a large
model with a high amount of elements
and special demands. The ship antenna is
an interesting example for the postprocessing
of shock analysis while the military
antenna structure, made of GFRP has been
optimized regarding its weight using topology-
as well as composite optimization
tools.
Finally, for the secondary structure example,
a pilot project from Sogeti HighTech
will be discussed where a metallic bracket has
been transformed to CFRP. Within the
project the bracket has been sized, manufactured
and tested. On this example the whole
process from structural concept,
pre-dimensioning, optimization and test
calculation will be shown.
