To better explore the influence of friction stir jointing process parameters on temperature field distribution in the jointing process, the forces acting on the tool and the friction coefficient between the shoulder and tool and the changes of the internal materials of workpiece with the temperature were considered. A heat source model was established to simulate and analyze the variation of temperature field with the process parameters of friction stir jointing. The heat source model was established. The simulation results showed that the temperature in the advancing side was higher than that in the retreating side. The peak of heat cycle curve gradually decreased from the surface to the bottom of workpiece. The rotation speed on the peak of heat cycle curve effect was small, and the feed speed was large. The accuracy of the heat source model of the friction stir jointing was related to the accuracy of the subsequent simulation analysis of the residual stress distribution and deformation of the connection. Therefore, this study has important theoretical significance. |
