摘要: A “33” mode single crystal lead magnesium niobate-lead titanate flextensional actuator with large displacement, high load capability, and broad bandwidth was designed, prototyped, evaluated at temperatures ranging from room temperature to cryogenic temperatures. Measuring 27.4 × 10 × 13.6 mm (height) overall weighing 9.2 g, the generates a 96.5 μm displacement in Z-direction 170 Vrms. The level of remained constant under compressive loads up 5 kg force. maintains 66% its −196 °C. measured displacements matched well those modeled using ANSYS finite element analysis.
