ANSYS铜钢感应加热温度场的数值模拟

摘要本文根据感应加热的基本原理，以及铜钢异种金属焊接过程中采用的高频感应熔敷焊工艺特点，利用电磁学，传热学等方面的知识和有限分析方法，以实际工件的尺寸以及焊接过程中与设备的相对位置为标准，按比例建立了铜钢高频感应熔敷焊的数学模型。在用ANSYS对温度场进行模拟时，用控制变量法分别探讨了时间，电源频率，线圈直径，线圈相对高度对温度场加热的影响，用以指导实际焊接。28244
简单陈述了感应加热的基本原理，并分析了温度场的有限元数学模型还有边界条件。另外还简要讲解了ANSYS软件的使用方法。
模拟检验：设定等同的焊接参数，进行实际焊接，并对实际焊接中钢基体内与铜带最高接壤处进行温度测量，得到该点的温度循环曲线，与焊接模拟中相对应的点的循环曲线进行比较，误差在10%以内，且温度变化的总体趋势大概一致。

Abstract This paper according to the basic principle of induction heating, and copper steel dissimilar metal welding process by high frequency induction cladding welding process characteristics, using electromagnetics, heat transfer, and other aspects of knowledge and the finite analysis method, to the size of the actual workpiece and welding process and equipment of relative position as the standard, according to the proportion of established the mathematical model of the copper steel high frequency induction cladding welding.When using ANSYS to simulate the temperature field, establish certain welding time and under the same other conditions set different parameters to simulate the temperature field under different parameters, investigate the effect of various parameters on the effect of induction heating, so as to guide the practical welding.
       A simple statement of the basic principle of induction heating, and analyzed the temperature field finite element mathematical model and boundary conditions. In addition, a brief explanation of the method of using ANSYS software.
      Simulation test: set the same welding parameters, for the actual welding and to the actual welding steel base body and a copper strip with highest border to measure the temperature, temperature cycle curve of the point, and welding simulation corresponds to the point of circular curve, error is less than 10% and the overall trend of temperature change probably.
Keywords: copper, steel, temperature field, ANASYS, numerical simulation
