【摘要】：研究船舶噪声源的识别。通过研究船舶噪声、参考信号的叠加形成船舶内响应信号,通过三者的关系建立传递率矩阵。船舶模型仿真实验来说明,以位移差为振源能有效的降低振源之间的耦合,减小了真实值和测量值之间的误差,有效证明了船舶噪声贡献传递率模型的正确性。
[Abstract]:The identification of ship noise sources is studied. By studying the ship noise and the superposition of the reference signal, the response signal of the ship is formed, and the transfer rate matrix is established by the relationship between the three. The simulation results of ship model show that using the displacement difference as the vibration source can effectively reduce the coupling between the vibration sources, reduce the error between the real value and the measured value, and effectively prove the correctness of the ship noise contribution transfer rate model.
