Abstract：

To solve the difficulty in forming the ship plate, the plate forming effect was improved by coupling thermal stress with external load, and the relationships between the distribution of temperature field with the heating power and heating time were studied by experiment. The research results show that the forming effect is remarkable at the temperature of 300-350 ℃，and the time of 12-16 s. Therefore, the relationships between the bending angle, curvature radius with temperature and moment were analyzed by fitting data. The relationship between displacement and curvature radius was derived and then the relative maths model was set up. At the same time, based on the above mathematical model, the deformation process of the plate was simulated by MATLAB curve surface fitting tool. At last, the simulation results are consistent with the experimental results.
