Abstract: For the problem that the surface temperature of material tape is so difficult to control in the process of laser heating and solidifying shell forming that influence the molding quality, we analyzed the related technological parameters that affected the surface temperature of the material tape during the forming process and deduced theoretically for their relationship. By the ANSYS finite element analysis software, we built a thermodynamic transient analysis model to simulate the surface temperature change of the material strip during the shell forming and analyzed the simulation results. We tested the temperature changes and the influence of temperature on the strength of the shell through experiments, and then compared the experimental data with the simulation results to verify the correctness of the simulation model, and get the relationship among the forming temperature of the surface of the material, the forming speed and the laser power, based on which the relationship between the molding temperature and the shell strength was deduced.

Key words: laser curing, the surface temperature, finite element analysis, shell strength
