| 摘 要： | 为了研究水下工程结构辐射声场的识别问题,基于相位共轭方法采用离散阵元对水下有限长圆柱壳的辐射声场识别进行了数值仿真计算.采用不同的阵列形式分别在近场和远场对圆柱壳表面声压、法向速度、辐射声功率和声强进行了识别及重构误差分析,并讨论了激励频率变化对重构结果的影响.数值计算结果表明:只有在近场采用圆柱形阵列形式并基于声压梯...

| Abstract: | The identification and reconstruction of the sound field radiated from a cylindrical shell underwater are studied numerically using discrete elements based on the phase conjugation method for the research of the identification of the radiation of the underwater structure.The surface pressure,the normal velocity,the radiation power,and the intensity of the cylindrical shell are reconstructed by using different array forms in the near and far field.The impact of the changing excitation frequency on the identi... |
