Abstract
The application of special thermoplastic engineering plastics promotes high-end manufacturing advancing to-wards light weight,high-performance,and environmental protection.To study the induction welding process between plas-tics and metals,better understand the influence of different parameters on the surface temperature of welded metals,and ex-plore the most suitable parameters for plastic induction welding,the finite element analysis software ANSYS Maxwell was adopted for electromagnetic field simulation,the central composite design method was employed to design the parameters for plastic induction welding,then the temperature of the corresponding metal surface was solved through the finite element analysis software.Based on the multivariate nonlinear theory,an iterative strategy of stepwise regression was adopted in the multivariate nonlinear regression model to analyze the impact of current intensity,current frequency,welding gap and their interactions on the average temperature of the metal surface.The results indicated that the quadratic model had the best fit with a determination coefficient of R2=0.956.The current intensity was the principal effect that had the greatest impact on the average temperature of the metal surface.The interaction between the current intensity and welding gap was the main in-teractive effect that affected the average temperature of the metal surface.Based on the quadratic model,multiple optimal pa-rameter combinations were predicted and then verified through the finite element analysis software.The deviation between the simulation experiment results and regression analysis results was within 7%,indicating a high accuracy and reliability of the quadratic model.The theories and methods related to this study provided a solid reference for the application of plastics in manufacturing fields such as automobiles,ships,aviation,and aerospace.关键词
