This work examines the porting of smart structures into design and
construction of next generation instrumentation for Astronomy. An
optical spherical mirror with actively deformable curvature has
been selected as representative benchmark for technological and
numerical investigation. The proper smart actuator to be adopted,
their embedding technology and the optical quality replica process
needed to its manufacturing are treated in this work including
numerical tools for the performance evaluation. Several
technologies can be considered to design smart structures, here
piezo-composites and SMA based actuators are evaluated. Numerical
and experimental techniques purposely developed to integrate
piezocomposites into smart structures are presented to exploit
their increased flexibility respect to monolithic PZT. Moreover the
technology developed for the embedding of SMA actuators in smart
structures including the interface analysis with the host material
is described. Some possible performance modelling approaches and
control systems of the actuators are addressed taking into account
trade-o between detailed analysis and overall performance
prediction as a function of the CPU time."
