中文摘要:

惯性的范围类型向量水中听音器的收到的理论的健全压力波浪和粒子速度波浪被学习。与共同震荡基于粒子速度水中听音器的测量原则范围,在一个自由地动人的声学的 planewave 领域里收到反应到僵硬范围和有弹性的范围的声波的数学表达式被导出,并且在速度水中听音器和它的几何尺寸和密度的频率反应曲线之间的关系被分析。根据收到球形的收到的变换器的理论的声波,另外,向量水中听音器收到反应的健全压力的数学表达式被导出,并且在收到向量水中听音器和参数的系数的压力之间的粒子速度水中听音器和关系的表面上的压力分发的法律例如收到的表面的尺寸,粒子速度水中听音器,布局位置和 rad 的半径收到向量水中听音器的理论的声波的分析方法被建立,它为向量水中听音器的设计和开发打理论基础。

英文摘要:

Sound pressure wave and particle velocity wave of the receiving theory of iner- tial sphere type vector hydrophone was studied. Based on measurement principle of particle velocity hydrophone with co-oscillating sphere, the mathematical expressions of sound wave receiving response to both rigid sphere and elastic sphere in a freely moving acoustic plane- wave field were derived, and the relationship between the frequency response curves of velocity hydrophone and its geometrical dimension and density was analyzed. In addition, according to sound wave receiving theory of spherical receiving transducer, the mathematical expression of the vector hydrophone's sound pressure receiving response was derived, and the laws of the pressure distribution on the surface of particle velocity hydrophone and relationships between the pressure receiving coefficient of the vector hydrophone and the parameters, such as the dimensions of the receiving surface, the radius of the particle velocity hydrophone, the layout position and radius of sound pressure hydrophone, were analyzed and calculated. The analysis method of sound wave receiving theory of vector hydrophone was established, which lays the theoretical foundation for design and development of the vector hydrophone.
