摘要
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2Ω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。
Mechanical energy of vibration is one of the most popular energies existing in the environment. To reduce its negative affect, the vibration is usually dissipated by artificial dampers, which are in fact the energy-wasting devices. In this research, a damper, which can transmit the vibration energy into electric energy, is proposed. This device is designed based on the hydraulic-electric generation principle. A prototype device is fabricated and tested in a testing platform. The experiment result shows that both the frequency and the resistance of the prototype device have the effect on collection of the electrical energy. The maximum instantaneous power of the device can reach 49 w in the condition of 2Ωload resistance and 1 Hz sinusoidal excitation. Hence, it is feasible to transform a part of vibration energy into electricity during the operation of the hydraulic-electric damper.
