Abstract

Transducers used actively in sonar systems are subject to prolonged transmission under high voltage, generating significant heat and experiencing temperature variations due to the operating environment. Piezoelectric single crystals exhibit changes in properties due to domain transformations, such as phase transitions, depending on the temperature. These changes affect the electrical and acoustic performance of transducers that use piezoelectric single crystals as active elements. In this study, the material constants of piezoelectric single crystals were derived under various temperature conditions, and the performance variations of transducers incorporating these constants were analyzed to investigate the impact of temperature changes on transducers. To this end, the electromechanical impedance of Mn: PIN-PMN-PT piezoelectric single crystal resonators polarized along the [011] crystal axis was measured at different temperatures. The complete set of physical constants was determined using the resonance method and optimization techniques based on the measured resonance frequency, anti-resonance frequency, and capacitance. The derived material constants were applied to a finite element model of a Tonpilz transducer to analyze the temperature-dependent characteristics of the transducer. Furthermore, a transducer structure insensitive to temperature variations was designed. This approach is expected to prevent the degradation of transducer efficiency and output due to temperature changes, thereby contributing to the performance stabilization of sonar systems.

[011]极化mn掺杂0.32PIN-0.39PMN-0.29PT单晶全材料常数的温度依赖性及其对水下Tonpilz换能器性能的影响

声纳系统中主动使用的换能器在高压下需要长时间传输，产生大量热量，并且由于操作环境而经历温度变化。压电单晶表现出的性能变化，由于领域的转变，如相变，取决于温度。这些变化会影响使用压电单晶作为有源元件的换能器的电学和声学性能。本研究推导了不同温度条件下压电单晶的材料常数，并分析了包含这些常数的换能器的性能变化，以研究温度变化对换能器的影响。为此，测量了沿[011]晶轴极化的Mn: PIN-PMN-PT压电单晶谐振器在不同温度下的机电阻抗。基于测量的谐振频率、反谐振频率和电容，采用共振法和优化技术确定了完整的物理常数。将导出的材料常数应用于Tonpilz换能器的有限元模型，分析了换能器的温度依赖特性。此外，还设计了一种对温度变化不敏感的传感器结构。这种方法有望防止换能器效率和输出因温度变化而下降，从而有助于声纳系统的性能稳定。
