Advances in Topology Optimization of Piezoelectric Smart Structures
Abstract:Piezoelectric materials have been widely used in precise driving, vibration control, precise positioning and other fields due to their high deformation accuracy, fast response, and easy fabrication into miniaturized devices. Changing the position, size, and shape of piezoelectric components in piezoelectric smart structures can effectively improve the mechanical properties of the system, which has attracted the attention and research of many scholars and engineers. Topology optimization, as a powerful automated design tool, has been successfully applied to the optimization design of piezoelectric smart structures. In this review, the research background and significance of the topology optimization of piezoelectric smart structures are firstly surveyed, then the analysis and active control methods of piezoelectric smart structures are briefly outlined. Afterwards, recent advances are systematically reviewed in the optimization of piezoelectric smart structures for static deformation control and vibration control, and design and optimization of piezoelectric energy harvesting devices. Finally, several important issues for future studies in topology optimization of piezoelectric structures are identified.
