摘　　要：对B10铜合金管坯旋轧成形过程进行三维热力耦合仿真模拟。在模拟分析中分别从等效应力、等效应变和变形温度等方面,将B10铜合金与目前生产成熟的TP2紫铜的模拟结果进行对比,掌握了铜合金管坯旋轧成形的变形规律。相应实验结果证明铜合金管坯有限元模拟具有很好的仿真预测价值,并可用于探索其它类型铜合金管坯旋轧成形规律。The three-roll planetary rolling process of copper alloy tube was simulated and analyzed by finite element method （FEM） . The comparsion contents between B10 and TP2 copper tubes included equivalent stress, equivalent strain and deformation temperature. The deformation rules of B10 copper alloy were obtained by simulation. The forcasting value of the simulation was approved by experiment results. So the finite element method can be used on other kinds of copper alloy tubes in three-roll planetary rolling process.
