“…In some closed situations, such as subways and mines, vibration energy harvesting is the best choice, and can also avoid some catastrophic accidents. Present methods of vibration energy harvesting are magnetoelectric, [22][23][24] piezoelectric, [25][26][27] magnetostrictive [28][29][30] and triboelectric nanogenerators. [31][32][33] In recent years, to overcome the problem of the narrow effective bandwidth of linear vibration energy harvesting, researchers have applied nonlinear structures to the field of vibration energy harvesting.…”

Due to technical limitation, existed vibration isolation and vibration harvesting (VIEH) devices have poor performance at low frequency. Therefore, this paper proposes a new multi-link-spring mechanism (MLSM), which can be used to solve this problem. The VIEH performance of MLSM under harmonic excitation and Gaussian white noise are analyzed. It was found that the MLSM has well vibration isolation performance under low frequency isolation, and the frequency band can be widened by adjusting parameters to achieve higher energy harvesting power. By comparing with two special cases, the results show that the MLSM is basically the same as the other two oscillators in terms of vibration isolation but has better energy harvesting performance under the multi-stable characteristic. The MLSM is expected to reduce the impact of vibration on high-precision sensitive equipment in some special sites such as subway and mine, and at the same time supply power to structural health monitoring device.
