dc.description.abstract
In order to increase aerodynamic efficiency, it is desirable to change the shape of the
contour of the wings of an airplane for different flight conditions. This for example can
be achieved by a compliant structure, which can be deformed without joints. In this
presentation, the mechanical structural optimization of such a compliant mechanism is
presented.
To achieve high deformability, a lattice structure geometry is developed, consisting of
repeated unit cells. For the material, the superelastic Nitinol is chosen, which allows high
strain recoverability and maximum strength. However, its nonlinear relation between
stress and strain, as well as the geometric nonlinearities resulting from the desired large
geometric deformations, make the formulation and solution of the optimization problem
challenging. Additional analysis and optimization complexity arise from the large difference
in length scale between the whole structure and a single unit cell.
This multiscale optimization problem is addressed by first optimizing the design of the
unit cell, where both shape and topology optimization methods are employed. The unit
cell is then parametrized, to allow a grading of its shape over the whole structure. To
handle the nonlinear structural response, the capabilities of the commercial tools Abaqus
and Tosca are used.
