Abstract

The present study demonstrates the feasibility of creating adaptive multimodal surface patterns on an otherwise featureless cylindrical shell surface with the help of surface-bonded piezoelectric actuators. These patterns can be tuned to transform into a periodic shape that spreads equally over the domain or can have the form of a localized dimple that is concentrated only over a portion of the domain of the structure. The possibility of controlling the number, location, and temporal order of these patterns by smart actuation is established. This tunability, in both topographic patterns and their feature locations, can offer dynamic and switchable functionalities for fruitful applications.

摘要

本研究证明了在表面粘合压电致动器的帮助下，在原本无特征的圆柱壳表面上创建自适应多峰表面图案的可行性。这些图案可以调整为周期性形状，在整个域上均匀分布，或者可以具有仅集中在结构域的一部分上的局部凹坑形式。建立了通过智能驱动控制这些模式的数量、位置和时间顺序的可能性。这种地形模式及其特征位置的可调性可以为富有成效的应用程序提供动态和可切换的功能。
