摘要 压电能量收集是微能量领域的研究热点。为了优化压电能量收集器的设计并提高其输出电压,对压电单晶悬臂梁进行了有限元仿真与分析,包括对压电单晶悬臂梁的最大应力,产生的最大电压,以及压电晶片的长度、基板的材质和压电晶片的粘结位置对输出电压的影响都作了详细的研究。仿真结果表明,有限元方法能为压电能量收集器件的优化设计提供重要的理论指导。 Piezoelectric energy harvesting is the hot topic in micropower field.In order to optimize the design of the piezoelectric energy harvester and improve the output voltage,the finite element simulation and analysis of the piezoelectric unimorph cantilever were made,including the maximum force,the maximum voltage of the piezoelectric unimorph cantilever and the influence of the length of piezoelectric ceramic,the materials of the substrate,and the distance from the left side of the piezoelectric cantilever on the output voltage were investigated in detail.The simulation results show that the finite element method can provide important theoretic instruction for optimizing the design of the piezoelectric energy harvester.
