摘　　要：根据压电材料的压电效应,设计了一种利用压电片将风能转换为电能,且能自动迎风的风向标式风压发电装置。建立了该装置的数学模型,基于力矩分析,导出了其满足自动迎风要求的参数关系式。装置利用风力吹动压电片震荡,通过能量收集电路收集压电片产生的电能供负载使用。通过对整个装置进行力矩分析及系统稳定性研究表明,该装置在任意风向情况下能自动迎风稳定运行,可满足路灯等小功率负载的供电要求。According to the piezoelectric effect of piezoelectric material , a vane-type wind power generator capa-ble of automatic windward was designed by using the piezoelectric plates to convert the wind power into the electric energy. The mathematical model of the device was established. Based on the moment analysis, the parameter rela-tion to satisfy the requirement of automatic wind was derived. The device took advantage of the wind-force to drive the piezoelectric plates vibrate and the energies generated from the piezoelectric plates were collected by the energy harvesting circuit and supplied for the load. The analysis of the moment and the investigation on the stability of the whole device show that the device can run stably into the wind under any wind direction, and it can meet the power supply requirements of small power loads such as street lamps.
