The use of bistable laminates is a potential approach to realize broadband piezoelectric based energy harvesting systems. In this paper the dynamic response of a piezoelectric material attached to a bistable laminate plate is examined based on the experimental generated voltage time series. The system was subjected to harmonic excitations and exhibited single-well and snap-through vibrations of both periodic and chaotic character. To identify the dynamics of the system response we examined the frequency spectrum, bifurcation diagrams, phase portraits, and the 0–1 test.

基于双稳态叠层板的能量收集装置动态响应实验分析

使用双稳态层压板是实现基于宽带压电的能量收集系统的一种潜在方法。在本文中，基于实验产生的电压时间序列，研究了附着在双稳态层压板上的压电材料的动态响应。该系统受到谐波激发，并表现出具有周期性和混沌特征的单井和瞬变振动。为了确定系统响应的动态，我们检查了频谱、分岔图、相图和 0-1 检验。
