| 摘 要： | 在建立中厚板GMAW温度场数值仿真模型的基础上,用ANSYS进行了数值模拟,并通过红外热像仪进行了实验验证。实验结果与模拟结果对比分析表明,温度场热循环曲线的形状、峰值温度及加热速度比较接近实测数值,冷却区段偏差稍大,证明所建立的数值仿真模型可以较好地模拟中厚板GMAW的温度场,为应力应变分析等其他焊接过程的数值分析打下了良好的基础。

| Abstract: | Based on the numerical simulation a model about GMAW temperature field of medium plate was established, and simulated by the software ANSYS and was verified by IR camera. Comparing experimental results and simulation results it shows that the shape of thermal cycle curve, the peak value of temperature and the rate of heating are very close to the measured values other than a little deviation of cooling sector. So it can be concluded that the established numerical simulation model is feasible for simulating the GMAW temperature field of medium plate, and makes a good foundation for stress--strain analysis and numerical analysis of the other welding process. |
