摘　　要：根据摩擦纳米发电机(TENG)在低频能源收集上的优势及涡激振动低启动流速的特性,提出一种基于涡激振动的摩擦纳米发电机海流能俘能装置,介绍此发电装置的结构以及工作原理,并运用COMSOL有限元仿真软件模拟出独立层式多光栅结构摩擦纳米发电机的输出特性。通过线性模组试验分析TENG摩擦面之间的正压力对电能输出的影响。最后,在循环水槽中进行模型试验,获得此发电装置模型的电能输出数据,发现该模型装置能够在低流速下输出百微瓦级功率的电能。Due to the substantial study performed by academics globally,triboelectric nanogenerators(TENGs)are attracting significant attention in area of ocean energy acquiring and utilization.According to the advantages of TENG in low-frequency energy harvesting,this study presents an ocean current energy capturing device using TENG based on vortex-induced vibration(VIV).The device's structure and working principle are clarified,and the output characteristics of the freestanding-layer TENG with multi-grating structure are simulated by COMSOL software.The effect of the pressure between the TENG friction surfaces on the electrical energy output is analyzed by means of linear module tests.Finally,experiment in a recirculating flume was conducted to obtain the electrical energy output data of the generator model.It is found that the model device can output the power of 100 microwatts at low flow rate.This study provides a new research idea for the collection and utilization of ocean current energy at low flow velocity.
