Abstract:

The emergence of a large number of smart materials endows traditional structures with diversified functions, vigorously promoting the research on smart structures in various fields. Focusing on smart structure shape control points, this paper first summarizes three strain based structure deformation reconstruction methods commonly used in intelligent structure shape monitoring: the modal method, the Ko displacement theory, and the inverse finite element method. The basic principles and research status of these methods are introduced, and the inverse finite element method is selected for this study after the advantages and disadvantages of the three methods are compared. Secondly, the research status of influence factors and optimization algorithms of actuator control deformation in piezoelectric intelligent structures is introduced. The piezoelectric intelligent structure is then used as the carrier to realize the self-sensing and self-actuation ability of the structure. Combining the advantages and disadvantages of different intelligent algorithms and the actual needs of comprehensive research on sensors and actuator layouts, we propose a comprehensive optimization strategy for piezoelectric sensors and actuator layouts. Finally, the difficulties in the layout optimization of piezoelectric sensors and actuators are discussed, and the future research and development prospects of piezoelectric intelligent structures are prospected.
