N2 - Deep double-curvature shells are commonly used as key components in many advanced aerospace structures and mechanical systems, e.g., nozzles, injectors, horns, rocket fairings. Spatially distributed micro-actuation of a laminated flexible deep double curvature shell is investigated and its control effectiveness is evaluated in this study. Dynamic equations of the smart double curvature shell system are presented and modal control forces of spatial segmented piezoelectric actuators are carried out based on a new set of assumed mode shape functions with free boundary condition. Using these assumed mode shape functions, mode shapes of a free-floating deep shell are illustrated. Finally, via numerical simulation, control effectiveness of distributed actuator patches with respect to various natural modes, actuator locations and other factors which influence precision control and active actuation behavior of flexible deep double curvature shell structronic systems is evaluated.
