针对一型深水结构物的水下声场计算与试验研究

Numerical analysis and acoustic test of sound field characteristics for some type of deepwater structure

基于三维声弹性方法对一型深水结构物100~600 Hz频段内的场点声压进行了数值计算研究,并在水池中进行了模型的声学测试,场点声压传递函数的计算结果和实测结果吻合良好,证明了三维声弹性方法求解水下复杂结构物声学问题的有效性和精确性。文中最后对模型的场点声压周向分布特性进行了计算研究。

The field sound pressure of some type of deepwater structure is obtained based on the three-dimensional sono-elasticity method. The acoustic test of the model was implemented in the experimental tank,and the reverberation corrected sound pressure data from the test are well conformed with the numerical result, which indicates the availability and accuracy of the three-dimensional sono-elasticity method on acoustic problems for complex underwater structures. Finally, the distribution character on circumferential direction of the field sound pressure is investigated in this work.
