Abstract

In order to study the influence of mechanical rectification and inertial on vibration energy recovery characteristics, based on the harvest vibration energy of backpack as background, two kinds of vibration energy harvester were designed by referring to the motion transformation forms of rack and pinion and ball screw. The vibration energy harvester combines a one-way clutch and inertia to convert the vibration energy from the backpack into electrical energy for use by the electronic device. By establishing a system mathematical model, the energy harvesting characteristics of the system were analyzed from the perspective of energy conversion, and the effects of mechanical rectification and inertial on vibration harvesting characteristics were simulated and analyzed. Finally, the effects of mass ratio, frequency and load resistance on the energy harvesting characteristics of the system were analyzed through experiments, and the energy harvesting characteristics of the two prototypes were compared. The test results show that the system has the best energy harvesting performance when the system excitation frequency is close to the natural frequency of the system. At the same time, the energy harvesting efficiency can be improved by matching a suitable inertia. Moreover, compared with the ball screw type prototype, the harvesting efficiency of the rack and pinion prototype is higher under the same system parameters.
