摘要

摘要对横截面积为 2 × 2 毫米的多层压电致动器进行了数值建模。研究表明，在压电致动器中使用间隙开关时，会观察到横向应变最大值的局部重新分布，从而导致控制元件的机械强度和可靠性降低。我们制作了具有相同线性尺寸的压电陶瓷梳，并测量了所开发元件的机械和电气性能。结果表明，与横截面较大的多层致动器相比，在控制电压为 300 V 时，由于压电致动器的有效极化面积减小，使用间隙开关方法的行程从 4 μm 减小到 1.5 μm。制造出的带导线换向的压电陶瓷梳，在 300 V 控制电压下的位移为 4.6-4.8 μm。

Simulation and Measurement of Stroke in Piezoceramic Combs with a Decrease in Cross-Sectional Area of Control Elements

Numerical modeling of multilayer piezoactuators with a cross-sectional area of 2 × 2 mm was carried out. It was shown that when interdigitated switching is used in piezoactuators, a local redistribution of transverse strain maxima is observed, which leads to a decrease in the mechanical strength and reliability of control elements. Piezoceramic combs with identical linear dimensions were produced and the mechanical and electrical properties of the developed elements were measured. It was revealed that stroke at a control voltage of 300 V decreases from 4 to 1.5 μm when using the interdigitated switching method in comparison with multilayer actuators of larger cross-section due to a decrease in the effective polarization area of piezoactuators. Piezoceramic combs with wire commutation were manufactured, where the displacement at a control voltage of 300 V was 4.6–4.8 μm.
