Research on Simulation and Optimization of Traveling Induction Heating Process for Welding Deformation Rectification in High Strength Steel Sheet

Abstract

To observe the evolution mechanism of physical fields in the welding deformation rectification process by a traveling induction heating, research on simulation models of welding—induction heating continuous process were carried out. High-strength steel plates were selected for welding deformation experiment and induction heating rectification experiment in turn, and the stress field and strain field distribution after various processes were measured and recorded. Then, according to the construction process, an integrated model of welding-induction heating based on moving mesh method was analyzed and established by Ansys FE software, moreover, another progressive integrated model established based on the re-defined element attributes method was studied, and the calculation accuracy of these models were compared as well as the characteristics were analyzed. The research results show that these two integrated models can accurately reflect the evolution law of each physical field in the process of welding and induction heating, and the re-defined element attributes method is more suitable for the research of welding deformation and induction heating rectification process.
