摘要

针对水下传感器稳定持续供能问题，对柔性圆管内置压电悬臂梁的压电俘能结构进行仿真分析.实验对单俘能结构、前置柔性和刚性阻流体时的俘能结构分别进行流固耦合仿真，并对前置阻流体的俘能结构进行压电耦合和收集电路的仿真分析.实验结果表明：前置刚性阻流体俘能结构的振幅响应大于前置柔性阻流体和单俘能结构的，当流速为1.1 m/s、阻流体和俘能结构之间的距离与阻流体直径的比为3~4时，产生的振幅响应和电压幅值分别为0.9 mm和85 V，此时频率为9 Hz，能量收集效率为36.18%，为涡致振动压电能量收集结构的最佳形式.实验结果证明了柔性圆管内置压电悬臂梁压电俘能结构的可行性，为水下传感器持续稳定的供能提供了一种解决方案.

ADINA 压电俘能结构流固耦合仿真压电耦合仿真标准能量收集电路

Abstract:

For the problem of stable and continuous power supply for underwater sensor networks,a simulation analysis of the piezoelectric energy harvester of a piezoelectric cantilever built into a flexible tube was carried out.The experiment conducted fluid-structure coupling simulation of the single-energy-harvester,the pre-flexible and rigid bluff bodywere carried out respectively.Then,the piezoelectric coupling and collecting circuit simulation analysis was carried out on the pre-bluffing energy harvester.The results show that the amplitude response of the energyharvester of the front rigid bluff body was greater than that of the front flexible bluff body and the single-energy-trapping structure.When the flow velocity was 1.1 m/s,the L/D was 3~4,the generated amplitude response and voltage amplitude were 0.9 mm and 85 V respectively.At this time,the frequency was 9 Hz,and the energy collection efficiency was 36.18%,which was the highest of the vortex-induced vibration piezoelectric energy harvester.It proved the feasibility of the piezoelectric energy harvester with the piezoelectric cantilever beam built into the flexible tube,and provided a solution for the continuous and stable energy supply of the underwater sensor network.
