以双压电晶片振子为研究对象,对悬臂梁式双压电晶片振子在正压电效应下电压输出特性进行了有限元分析与试验研究,给出了压电晶片在悬臂梁上的最佳粘贴位置,并且利用有限元分析软件建立了悬臂梁双压电晶片振子的有限元模型,进行了结构尺寸参数对悬臂梁双压电晶片振子输出电压影响规律的仿真分析;利用压电陶瓷发电能力测试系统进行了试验测试,通过仿真和试验结果对比分析,得出了结构尺寸参数对悬臂梁双压电晶片振子发电的输出电压影响规律。
The bimorph oscillator is investigated,in the piezoelectric effect voltage output character of bimorph oscillator based on cantilever beam was studied by the finite element analysis and experimental.The best position of piezoelectric oscillator pasted on the cantilever was given,the finite element model of was established by using of finite element analysis software,the impact of the structure and size parameters on the piezoelectric cantilever oscillator voltage output effects was simulated.Relative experimental tests were carried out using test system of piezoelectric ceramic generating capacity,by comparison of simulation and test results,the structure and size parameters on the impact of bimorph oscillator cantilever voltage output effects was obtained.
