摘　　要：压电材料受到激振力作用时,压电材料的往复变形在其极面上不断激发电荷,利用二极管桥式电路将该电能储存在储能电容内,并作为微功耗负载的供电电源。研究了激振式压电发电机的工作原理;给出了圆形金属和压电材料复合板在均布激振力作用下的压电发电机原理方案和求解复合板应力的数学模型;推导了激振式压电发电机的发电功率计算公式。When a vibration force acted on piezoelectric material,which will deform to-and-fro and excite electricity on its polar surfaces.Using diode bridge circuit charges the electricity to a storage energy capacity,which can be the power supply of micro-power circuit.Studied on the principle of piezoelectricity vibration generator,they were put forward that a principle project of a round complex board piezoelectric generator and a math model of solving the board stresses. And the formula of calculating generating power was deduced.
