| Abstract: | With the rapid development of ships and marine technology, higher requirement for vessel model is proposed, in order to eliminate noise and other adverse factors of test data and obtain accurate data for modeling, a new method of data preprocessing based on the wavelet threshold denoising is presented. By means of simulation, the related identification of ship model in the denoising identification is compared with the undenoising identification, and this method can apply parameter identification into trailing suction hopper dredger variable draft motion simulation, the effectiveness of the wavelet threshold denoising in the trailing suction hopper dredger parameter identification is verified. |

| Keywords: | Ship mathematical model Wavelet threshold denoising Data preprocessing Parameter identification Trailing suction hopper dredger variable draft motion |
