摘　　要：采用DEFORM-3D对重载汽车前轴精密辊锻-模锻成形过程进行三维有限元热力耦合模拟,逐步分析整个成形过程中的金属流动情况、温度场分布、应变场变化等,为模具设计及设备选取提供理论依据。The three dimensional thermo-mechanical coupled simulation of the heavy automobile front axles precision roll forging-die forging forming process is carried out by using the finite element method simulation software DEFORM-3D to analyse and solve the problems encountered in the forming process. Analyse the situation of metal flow, the temperature field and equivalent stress and strain field in whole forming process to provide the theory basis and guidance to actual production of the heavy automobile front axle precision roll forging-die forging forming process, die design and equipment selection.
