DP590双相钢焊接的数值模拟与试验测试

Numerical simulation and experimental test of DP590 dualphase steel welding

    摘要
  • 摘要: 采用ANSYS大型通用有限元分析软件,利用APDL语言对3.8 mm厚DP590双相钢板对接焊的焊接温度场进行了模拟计算,将生死单元技术和体生热率相结合来模拟焊缝的逐步填充过程和焊接热输入.为了验证模拟计算结果的准确性,进行了3.8mm厚DP590双相钢板的对接焊试验,焊接方法选用焊条电弧焊,利用热电偶、XSR30无纸记录仪测定了距离焊缝不同位置处的温度变化.结果表明,计算的温度场和试验测得的温度场变化规律基本一致.利用ANSYS计算焊接温度场来预测实际焊接过程中焊件的温度变化是可行的.

     

    Abstract: DP590 dual-phase steel weld temperature field was analyzed by using ANSYS softwere. A program was developed with APDL language supported by the ANSYS, combining the body heat rate and element birth and death technology to simulate the welding filling process and heat input. A butt welding experiment with the DP590 dual-phase steel (3.8 mm thickness) was done in order to verify the accuracy of the simulation calculation. It is verified that numerical simulation is feasible.
