埋入式温差发电系统设计与试验
|
摘要
为解决沥青路面无线传感器应用中电池供电寿命限制的问题,提出了一种利用沥青路面内部热能的埋入式温差发电系统。建立了反映沥青路面温度场分布的有限元分析模型;并搭建了沥青车辙板与埋入式温差发电系统的模型实验平台,通过热载荷模拟和实验分析对系统性能进行了研究。结果表明,埋入式温差发电系统可产生有效的输出电压;随着压强载荷的增加,系统的输出性能显著提升,而提升车辙仪的速度会降低系统的输出性能;在同一温度载荷下,压强对系统的影响程度大于行车仪速度的影响。
In order to solve the problem of battery life limitation in the wireless sensor application of asphalt pavement,a buried temperature difference power generation system utilizing the internal thermal energy of asphalt pavement was proposed. A finite element analysis model reflecting the temperature field distribution of asphalt pavement was established,and an overall model experimental platform for asphalt slab and buried temperature difference power generation system was built. System performance is fully investigated by thermal load simulation and experimental analysis. As a result,the buried temperature difference power generation system can generate an effective output voltage; as the pressure load increases,the output performance of the system increases significantly,and the speed of the rutting instrument increases the output performance of the system; under the same temperature load,The impact of the pressure on the system is greater than the impact of the speed of the vehicle.
