摘　　要：采用自适应的热源模型,利用msc·marc模拟了6 mm 2A14铝合金的双轴肩搅拌摩擦焊温度场。随后对模拟所得的温度场进行了试验验证,在相同的工艺参数下测量了焊接过程中距焊缝不同位置处的热循环曲线和峰值温度。对比结果表明:该模型能准确地模拟双轴肩搅拌摩擦焊接过程中的温度分布情况。The bobbin tool friction stir welding temperature field of 6 mm 2A14 Al work plate was simulated by msc·marc,which provides useful information for the investigation of welding process.Self adaptive heat source model and temperature dependent properties of the material were considered for the simulation.Bobbin FSW experiments were carried out to validate the calculated results,and the calculated results showed good agreement with the experimental results.
