【摘要】：研究船舶噪聲源的識別。通過研究船舶噪聲、參考信號的疊加形成船舶內(nèi)響應(yīng)信號,通過三者的關(guān)系建立傳遞率矩陣。船舶模型仿真實(shí)驗(yàn)來說明,以位移差為振源能有效的降低振源之間的耦合,減小了真實(shí)值和測量值之間的誤差,有效證明了船舶噪聲貢獻(xiàn)傳遞率模型的正確性。
[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.
