摘要

本文对高频感应焊接过程进行了数值研究。数学模型包括麦克斯韦方程的谐波矢量势公式，以及通过焦耳热项和非线性构成关系耦合的准静态对流主导热方程。它的主要创新之处在于采用了一种新的分析方法，可以根据 Vee 开口角度和额外的回弹效应计算空间变化的进给速度。此外，有限元离散化的数值稳定方法允许考虑现实的焊接线速度，从而对管材焊接过程进行相当全面的三维模拟。

Numerical simulation of high-frequency induction welding in longitudinal welded tubes

In the present paper the high-frequency induction welding process is studied numerically. The mathematical model comprises a harmonic vector potential formulation of the Maxwell equations and a quasi-static, convection dominated heat equation coupled through the Joule heat term and nonlinear constitutive relations. Its main novelties are a new analytic approach which permits to compute a spatially varying feed velocity depending on the angle of the Vee-opening and additional spring-back effects. Moreover, a numerical stabilization approach for the finite element discretization allows to consider realistic weld-line speeds and thus a fairly comprehensive three-dimensional simulation of the tube welding process.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
