近年来，多方向多自由度振动能量采集技术引起了越来越多的研究兴趣。提出了一种基于并联机构的压电六自由度振动能量采集器的原理，将六自由度振动能量转换为能量采集器上肢体的单自由度振动能量并输出电压。建立了压电式六自由度振动能量采集器的动力学模型，用于肢体的振动估计。在此基础上，开发和探索了斯图尔特型压电六自由度振动能量采集器。为了验证所建立的动力学模型和分析结果，利用SimMechanics建立了Stewart型压电六自由度振动能量采集器的仿真模型，并在不同的振动激励下进行了测试，进行了初步的实验研究。结果表明，所建立的动力学模型可以对压电六自由度振动能量采集器上肢体的振动进行估计。研制的Stewart型压电六自由度振动能量采集器可采集共振频率为17 Hz、25 Hz和47 Hz的多方向线性振动和多轴旋转振动能量。此外，所研制的压电六自由度振动能量采集器的谐振频率不受振动激励方向的影响。
Multi-directional and multi-degree-of-freedom (multi-DOF) vibration energy harvesting are attracting more and more research interest in recent years. In this paper, the principle of a piezoelectric six-DOF vibration energy harvester based on parallel mechanism is proposed to convert the energy of the six-DOF vibration to single-DOF vibrations of the limbs on the energy harvester and output voltages. The dynamic model of the piezoelectric six-DOF vibration energy harvester is established to estimate the vibrations of the limbs. On this basis, a Stewart-type piezoelectric six-DOF vibration energy harvester is developed and explored. In order to validate the established dynamic model and the analysis results, the simulation model of the Stewart-type piezoelectric six-DOF vibration energy harvester is built and tested with different vibration excitations by SimMechanics, and some preliminary experiments are carried out. The results show that the vibration of the limbs on the piezoelectric six-DOF vibration energy harvester can be estimated by the established dynamic model. The developed Stewart-type piezoelectric six-DOF vibration energy harvester can harvest the energy of multi-directional linear vibration and multi-axis rotating vibration with resonance frequencies of 17 Hz, 25 Hz, and 47 Hz. Moreover, the resonance frequencies of the developed piezoelectric six-DOF vibration energy harvester are not affected by the direction changing of the vibration excitation.
