复合铝合金薄壁管在高频感应焊中温度场的模拟

Simulation of temperature field in high frequency induction welding process of composite aluminum alloy thin-walled tube

复合铝合金薄壁管高频感应焊接过程中,焊接温度是影响焊接质量的主要因素。采用有限元分析软件ANSYS模拟其温度场,考虑薄管一次焊透和热计算的边界条件,利用线热源模型加载计算,得出焊接过程的温度分布和热循环曲线,这为进一步分析焊接应力应变提供了相应的理论依据。

Welding temperature is the main factor that influences the welding quality in high frequency induction welding process of composite aluminum alloy thin-walled tube. The finite element analysis software ANSYS was used to simulate the temperature field . One complete penetration of thin-walled tube and boundary conditions of thermal calculation were taken into account. Then a linear thermal model was used to load and calculate to draw the temperature distribution and thermal cycle curves of welding process. Research results provide the corresponding theoretical basis for further analysis of welding stress and strain.
