摘　　要：为提高大型船舶外板成型加工生产效率,建立自重成型预报系统,文中分析确定船体外板自重成型各种影响参数,以实船板自重数值实验数据为样本,应用曲线估计和多元线性回归方法,分析各几何参数与成型间的函数关系,建立船体外板自重成型的数学模型.与其他建模方法进行比较可以看出,文中所建回归模型误差明显降低,满足工程精度需要,具有实际应用价值.实测分析表明,数学模型预报结果与实验结果符合较好.目前,该成果已应用于船厂生产实践.To increase the rate of production for the forming operation in the shipbuilding process and set up a dead load forming forecast system, in this paper, data of effective parameters in dead load forming are measured. Mathematical models are constructed with curve estimate and multi-variable stepwise regression analysis method, based on the database of the calculation of dead load forming for hull steel plates. By comparing with other modeling methods, it is shown that Models in this paper have lower error ratio obviously, satisfy the engineering precision demand, and have application value. It is also shown that the numerical results agree with experimental results and have been applied to production.
