摘　　要：利用ABAQUS建立三维仿真模型,对304不锈钢进行热拉伸仿真模拟。结果表明,在1100℃、拉伸速率为15mm/s时,304不锈钢塑性得到极大提升。在热拉伸的基础上,对304不锈钢进行冲压模拟,分别设置温度在1100℃、形变速率为15mm/s和常温下两组模拟,结果表明热冲压拉伸深度为9.31560mm,最大应力为160.9MPa;冷冲压的拉伸深度为4.27264mm,最大应力为347MPa,热冲压材料塑性明显高于冷冲压。ABAQUS was used to establish a three-dimensional simulation model to simulate the hot stretching of 304 stainless steel.The results show that the plasticity of 304 stainless steel is greatly improved at 1100℃ and a stretching rate of 15mm/s.The results show that the plasticity of 304 stainless steel is greatly improved at 1100℃ and a stretching rate of 15mm/s.On the basis of hot stretching,stamping simulation of 304 stainless steel,respectively,set the temperature at 1100 C,deformation rate of 15mm/s and room temperature under the two groups of simulation,the results show that the hot stamping tensile depth of 9.31560mm,the maximum stress of 160.9MPa;cold stamping of the tensile depth of 4.27264mm,the maximum stress of 347MPa,the hot stamping plasticity of materials Obviously higher than the cold stamping.
