应用ANSYS参数化设计语言(APDL)编程并模拟仿真焊接过程中的温度变化。以模拟20 g(20锅炉板)焊接为例,建立三维模型、网格划分、施加高斯热源、控制载荷移动,实现焊接过程的数值模拟。通过改变程序中的参数变量,得出焊接速度、电弧有效加热半径、焊接电压、焊丝材料对焊接温度场的影响,为焊接工艺的改善提供重要的理论依据。
Programming with ANSYS Parametric Design Language (APDL) and simulating temperature changes during welding. Taking the welding of 20 g (20 boiler plate) as an example, a three-dimensional model was established, meshed, Gaussian heat source was applied to control the movement of load, and the numerical simulation of welding process was realized. By changing the parameter variables in the program, the influence of the welding speed, the effective heating radius of the arc, the welding voltage and the welding wire temperature on the welding temperature field is obtained, which provides an important theoretical basis for the improvement of the welding process.
