Finite element studies have been conducted on the $\left(B{a}_{0.85}C{a}_{0.15}\right)\left(T{i}_{0.9}Z{r}_{0.1}\right){O}_{3}$(BCTZ) material fabricated at different sintering temperatures. BCTZ materials calcined at $1300\,^\circ {\rm{C}}$ for two hours and sintered at four different temperatures viz. $1520\,^\circ {\rm{C}},$ $1530\,^\circ {\rm{C}},$ $1540\,^\circ {\rm{C}}$ and $1550\,^\circ {\rm{C}}$ for two hours were considered. The structure was subjected to base vibration and its dynamic effect was studied. Sensing, energy harvesting and actuation capabilities of the system was studied. It was observed that BCTZ material sintered at ${1540}^{o}{\rm{C}}$ demonstrated maximum values for sensing voltage, actuation displacement and harvested energy. Actuator displacement was measured in terms of tip displacement of the cantilever beam. Compared to BCTZ material sintered at ${1520}^{o}{\rm{C}}$ for two hours, sensing voltage increased by about $81 \% $ in ${d}_{31}$ mode and $30 \% $ in ${d}_{33}$ mode. Similarly, harvested power increased by about $238 \% $ in ${d}_{31}$ mode and $60 \% $ in ${d}_{33}$ mode. Actuation displacement in ${d}_{31}$ mode was found to be more than that in ${d}_{33}$ mode. It was observed that fabrication method has a profound effect on the material which can enhance the energy harvesting and sensing capabilities.

烧结温度对 (Ba0.85Ca0.15)(Ti0.9Zr0.1)O3 陶瓷传感、驱动和能量收集性能的影响:基于数值和模拟的研究

已经对$\left(B{a}_{0.85}C{a}_{0.15}\right)\left(T{i}_{0.9}Z{r}_{0.1}\right){O}_{ 3}$在不同烧结温度下制造的(BCTZ) 材料进行了有限元研究。BCTZ 材料在 10 ℃ 下煅烧$1300\,^\circ {\rm{C}}$两小时并在四种不同温度下烧结,即。$1520\,^\circ {\rm{C}},$ $1530\,^\circ {\rm{C}},$ $1540\,^\circ {\rm{C}}$$1550\,^\circ {\rm{C}}$考虑了两个小时。对结构进行基础振动,研究其动力效应。研究了系统的传感、能量收集和驱动能力。据观察,BCTZ 材料在${1540}^{o}{\rm{C}}$传感电压、驱动位移和收集能量的最大值下烧结。根据悬臂梁的尖端位移测量执行器位移。与在${1520}^{o}{\rm{C}}$2 ℃ 下烧结两小时的BCTZ 材料相比,感应电压$81 \% $${d}_{31}$模式和$30 \% $${d}_{33}$模式。同样地,收获的功率增加约$238 \% $${d}_{31}$模式$60 \% $${d}_{33}$模式。${d}_{31}$发现模式中的驱动位移大于模式中的位移${d}_{33}$。据观察,制造方法对材料具有深远的影响,可以增强能量收集和传感能力。
