摘要
根据仿真设计和计算结果,制备了悬臂梁结构压电陶瓷复合材料,并考察了其振动发电性能。对复合材料的内外阻抗进行匹配,获得了最大的功率输出并在最佳阻抗匹配条件下,研究了振动发电性能与激励振幅和频率的关系。研究结果表明,压电复合材料的振动发电功率随着激励振幅的增大呈二阶增大,随着激励频率的增大呈线性增大。
A piezoelectric ceramic composite material of cantilever beam structure has been prepared based on the simulation design and calculation results and its vibration generating perfornance studied. By matching the external and the internal impedance of the composite,the maximum output power is obtained. Under the optimum impedance matching condition,the research on the relationship between the vibration power generating performance and the excitation amplitude and frequency are carried out. The results show that the electric power generated from vibration of piezoelectric ceramic composite has a two-order increase with the increase of amplitude,and a linear increase with the increase of the excitation frequency.
