| 摘 要： | 针对静水压力对声纳换能器工作特性的负面影响,提出闭式水下气体压力补偿方案以平衡换能器内外压力,并通过对系统工作过程的热力学分析以及对空气压缩机与比例压力阀等关键元件控制策略的研究,建立了换能器水下气体压力补偿系统的数学模型.仿真结果表明,闭式水下气体压力补偿系统可满足换能器内外压力平衡的精度要求,系统压缩空气可实现循环工作;空气压缩机的排气量、高压腔的容积是影响系统压力补偿响应特性的关键因素.

| Abstract: | Aiming to reduce the negative influence induced by hydrostatic pressure on sonar transducer, a new approach of air pressure compensation was designed based on the thermodynamics and mechanics analysis of the working process of the system and the research on the key components as air compressor and proportional pressure valve, and mathematical model of the system was built up.The working characteristics of the system were researched on by the simulation.The results show that the design can meet the required precision and the air can be used circularly.The flow rate of the compressor and the volume of high pressure chamber are the key factors affecting the characteristics. |
