Abstract In this paper, the stress behaviour and power generation of cymbal bimorph transducer of different piezoelectric ceramics are studied. Comparison of stress, deformation and power is done between different materials cymbal bimorph transducer. The cymbal bimorph design is made on Solidworks, and simulation is carried out on ANSYS 18.0. In this design, the substrate thickness is varied. Its both end surface is bonded to the piezoelectric layers of 0.50 mm thickness and further piezoelectric layers bonded to endcaps. A 100 N of the load is applied at the apex of end caps. The lead-free ceramics and lead-based ceramic are used as a piezoelectric material in the design. The stress and power are calculated for different values of thickness of the substrate, and comparison is made among them. After having a comparison it is found that both types of ceramics can be used, but there are some conditions which prioritise lead-free ceramic over lead-based ceramic.

用于能量收集的无铅陶瓷钹换能器的有限元分析

摘要 本文研究了不同压电陶瓷镲片双压电晶片换能器的应力行为和发电情况。不同材料的钹双压电晶片换能器的应力、变形和功率比较。钹双压电晶片设计在 Solidworks 上进行，仿真在 ANSYS 18.0 上进行。在这种设计中，基板厚度是变化的。它的两个端面与 0.50 毫米厚的压电层结合，另外的压电层与端盖结合。在端盖的顶点处施加 100 N 的载荷。无铅陶瓷和铅基陶瓷在设计中用作压电材料。计算不同基板厚度值下的应力和功率，并进行比较。
