摘要:
针对传统悬臂梁振动发电频带窄的问题,提出了一种弹性折叠梁结构。仿真分析了该结构的振动特性,探讨了结构参数变化对共振频率的影响,搭建了振动发电测试系统,通过实验验证了该结构的发电能力。实验结果表明,相较于传统悬臂梁,弹性折叠梁具有更低的共振频率,利用多个频率接近的模态可以显著拓宽频带宽度,在振动发电方面具有明显优势。
Abstract:
In regard of narrow bandwidth of traditional cantilever beam, this paper presents an elastic folded beam. Firstly, vibration characteristics of the proposed structure were simulated and influences of structural parameters on the resonant frequency were discussed. Then, a system was established to test the vibration power generation. Finally, the power generation capacity of the structure was verified through experiments. The experimental results show that compared with the traditional cantilever beam, the proposed one has lower resonance frequencies, and the band width can be significantly broadened by the multi-modal effect, which has obvious advantages in vibration power generation.
