摘要 描述了使用有限元方法(FEM)模拟钢管在曼内斯曼式穿轧机上的穿孔过程,建立了三维有限元模型,并考虑了在金属成形过程中出现的热力学现象.模拟的结果动态地显示了在工件内部等效应变、等效应变率和温度的分布.基于这些参数,分析了钢管的穿孔过程,同时通过实验测试与有限元模拟的结果进行对比.结果表明,测试的结果与有限元模拟的结果比较吻合.

关键词 热力耦合模拟有限元方法(FEM)分析钢管穿孔过程    
Abstract:The finite element method(FEM) is used for simulation of piercing process of the tube in Mannesmann mill.The numerical model is described and takes into consideration for example thermal phenomena present in metal during forming.The simulation results visualize dynamic distributions of equivalent strains,equivalent strain rates and temperature,especially inside the workpiece.On the basis of the basic parameters,the phenomenon in the piercing process is analyzed.The model was verified by comparing the values of calculated force parameters of the piercing process and those measured in laboratory conditions.
