AI 中文摘要
本文提出了一种用于管材高频感应焊接仿真的三维多物理场有限元框架。该模型将时谐磁场标量势公式与稳定的准稳态对流-扩散热传输方程耦合，能够在工业操作条件下准确预测电磁场和温度场。该框架包含参数化几何生成和半自动、物理定制的网格构建，并使用开源工具GetDP和Gmsh实现。针对AISI 304不锈钢管的商业感应焊接生产线的测量数据进行的验证表明，模型与操作数据吻合良好。随后，将经过验证的模型应用于研究感应器材料的影响，比较了传统FeNiZnV铁氧体与软磁复合材料Ferrotron 559H在AISI 304不锈钢管感应焊接中的表现。
英文摘要
A three-dimensional multiphysics finite element framework for the simulation of high-frequency induction welding of tubes is presented. The model couples a time-harmonic magnetic scalar potential formulation with a stabilized quasi-stationary advection-diffusion heat transport equation, enabling accurate prediction of electromagnetic and thermal fields under industrial operating conditions. The framework incorporates parameterized geometry generation and semi-automated, physics-tailored mesh construction and is implemented using the open-source tools GetDP and Gmsh. Validation against measurements from a commercial induction welding line for AISI 304 stainless steel tubes demonstrates good agreement with operating data. The validated model is subsequently applied to investigate the influence of impeder material by comparing a conventional FeNiZnV ferrite with the soft magnetic composite Ferrotron 559H for the induction welding of AISI 304 stainless steel tubes.
