摘　　要：作为连续挤压成形零件的模具、挤压轮及堵头所受的成形力分析是其进行结构设计的关键。建立了铝合金扁线连续挤压成形的有限元模型,并应用有限元分析软件DEFORM-3D对铝合金挤压的变形过程进行了三维模拟,获得了铝扁线挤压过程中的挤压模具、挤压轮及堵头所受成形力的行程曲线,该行程曲线对挤压机模具、堵头、挤压轮的合理、优化设计提供依据。As the important parts of continuous extrusion forming, validation of forming load on tool and die is the key of their design. This paper build the computer finite element analysis model of continuous extrusion forming by way of aluminous flat wire, the finite element software,DEFORM-3D,simulated the deformation process of aluminum profiles. The curves of pressure-stroke in the extrusion processes were obtained. All these can provide the foundation of structure optimization design of die, extrusion wheel and abutment.
