Abstract
In view of the characteristics of high energy density, high piezoelectric constant, low frequency constant and good low frequency performance of PMN-PT piezoelectric monocrystal material, this paper studies the corresponding technology from the perspective of engineering application. Aiming at the weakness of PMN-PT piezoelectric monocrystalline material, such as low phase transition temperature, low coercivity field and fragile, and combining with specific application background and demand, the solution is given. A batch of PMN-PT piezoelectric monocrystal transducers were developed and tested for its voltage-resistance, temperature stability and acoustic performance. The results show that the PMN-PT piezoelectric monocrystalline material has obvious advantages of acoustic performance of transmission and reception, it also reflects good low-frequency broadband characteristics and can be used in the high-power composite rod matching layer broadband transducer. The research results can be used to guide the application of PMN-PT piezoelectric monocrystal in sonar.
