为建立船舶四自由度响应数学模型，采用模拟建模法建立船舶横摇响应数学模型，首次提出横摇指数的概念，然后对8艘船舶进行SPSS多项式回归和偏最小二乘回归，得到回归方程，最后将Nomoto模型与船舶横摇响应数学模型相结合，得到船舶四自由度响应数学模型。与传统的船舶水动力数学模型相比，该模型简单易行，基本满足精度要求。
In order to build a 4 degrees responding mathematical model for ships,the paper establishes a responding mathematical model for ship roll by analog modeling method,and puts forward the concept of the indexes of rolling for the first time.Then,the regression equations of are obtained by doing SPSS multinomial regression and Partia least-squares regression(PLS) of 8 ships.Finally,a 4 degrees responding mathematical model for ships is got by combining Nomoto model and the responding mathematical model for ship roll.Comparing with the traditional ship hydrodynamic mathematical model,the proposed model is simple and easy to analyze,which can basically meet accuracy requirements.
