振动能量回收的液电减振装置设计与测试

振动能是环境中广泛存在的，为了减小振动的负面影响，这些振动能常常被人们设计的减振装置所耗散，造成了能量浪费。提出一种能够将振动能转换成电能的减振装置，采用液压传动发电的原理进行设计，制作了试验样机，并在实验平台上进行测试。实验结果表明，振动激励频率和负载电阻对收集的电能都有影响，当采用2 Ω负载电阻，频率为1 Hz的正弦振动激励条件下，最大瞬时发电功率可达到49 W。因此，将减振装置运行过程中的部分振动能转换为电能是可行的。

Design and Test of a Hydraulic-electric Damper with Vibration Energy Recovery

Abstract: Mechanical energy is one of the most popular energies existing in the environment. To reduce its damage effect, the vibration has been dissipated by the man-made damper, which is in fact a energy-wasting device. In this research, a damper that is capable of harvesting vibration energy was proposed. The device was designed in accordance with the hydraulic-electric generation principle. A prototype device was fabricated and tested in a set-up. The experiment result turns out that both the frequency and the resistance have the effect on the harvested electrical energy. The maximum instantaneous power 49w was obtained at the condition of 2Ω load resistance and 1Hz sinusoidal excitation. Hence it is feasible to transform part of vibration into the electricity during the operation of the damper.
