Abstract
This work presents a comparison of two beam
codes for aero-servo-elastic frameworks: a
new structural model for the aeroelastic code
HAWC2 and a new nonlinear beam model,
BeamDyn, for the aeroelastic modularization
framework FAST v8. The main goal is to establish
the suitability of the two approaches to
model the structural behaviour of modern wind
turbine blades in operation. Through a series
of benchmarking structural cases of increasing
complexity, the capability of the two codes
to simulate highly nonlinear effects is investigated
and analyzed. Results show that even
though the geometrically exact beam theory
can better model effects such as very large
deflections, rotations, and structural couplings,
an approach based on a multi-body formulation
assembled through linear elements is capable
of computing accurate solutions for typical nonlinear
beam theory benchmarking cases.
