Abstract: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.
