摘要
Low-frequency vibration energy is ubiquitous in surroundings. However, it is a consensus that obtaining a satisfactory efficient of energy harvesting at ultra-low ambient frequencies remains challenging. Therefore, a solution to this problem is proposed, which is to increase the working frequency by converting the low-frequency excitation into self-excited vibration of friction systems. Inspired by the idea, a lumped parameter model is developed to confirm the feasibility theoretically, and the characteristics of the output voltage and power is analyzed and simulated based on the numerical model. An energy harvesting experiment where the excitation comes from the vibration induced by reciprocating sliding friction is performed, for comparison, an impact-driven energy harvesting experiment is also conducted, to confirm the efficacy of improving the output power by converting the ultra-low-frequency excitation into friction-induced vibration of friction systems. Both the experimental and numerical results indicate that the working frequency can be tremendously improved via friction-induced vibration, and the amplitude of the voltage generated by the friction-induced vibration is positively correlated with the excitation frequency. Compared with the voltage generated by the impact, the voltage generated by the friction-induced vibration owns lower amplitude but much higher frequency. Thanks to the frequency-up-conversion effect, the output power of the energy harvester is improved significantly, which enhances the performance of the energy harvester at ultra-low ambient frequencies. © 2021 Journal of Mechanical Engineering.
