【摘要】 水下爆炸可对舰船以及舰船设备等结构造成严重毁伤,严重危及舰船的生命力和作战能力。高频压电换能器基阵主要采用压电复合材料作为功能元件。压电复合材料的抗冲击能力是高频换能器抗冲击的关键。本文通过结构设计、功能元件设计以及背衬设计增强高频换能器的抗爆炸冲击能力,试验验证了换能器阵的水下抗爆炸冲击能力,重点测试了换能器阵元的在爆炸前后的静态电容和工作点电导变化,结果表明:1-3型压电复合材料阵元的静态电容均降低,降低幅度在3%以内;工作点电导有增也有减,但变化幅度均在±6%以内。更多还原

【Abstract】 Underwater explosion can cause serious damage to ships and ship equipment, and seriously endanger the vitality and combat capability of ships. High frequency piezoelectric transducer arrays mainly use piezoelectric composites as functional components. The impact resistance of piezoelectric composites is the key to the impact resistance of high frequency transducers. In this paper, the structural design, functional element design and back-up design are used to enhance the anti-explosion impact ability of high-frequency transducers. The underwater antiexplosion impact ability of transducer array is verified by experiments. The static capacitance and conductivity change of working point of transducer array element before and after explosion are mainly tested. The results show that the static capacitance of 1-3 piezoelectric composite array element is reduced by less than 3%; The conductance at the operating point increases and decreases, but the change range is within ± 6%.更多还原
