摘　　要：针对板式翅片加工现状,提出一种板式翅片滚压成型新方法。阐述了该方法的成形原理;在三维软件中建立了滚压刀具和工件的有限元分析模型,采用Deform-3D有限元分析软件对板式翅片滚压成型过程进行了数值仿真,获得了理想的翅片形状;分析了成形过程中工件的应力状态及滚压刀具的受力情况,为板式翅片滚压成型方法的研究和应用提供了重要理论依据。Aiming at the present status of plate-fins processing, a new method for rolling forming of plate-fins is presented. The rolling forming principle of this new method is expatiated. The finite element analytical models of rolling tool and workpiece are established in three-dimensional software. The numerical simulations of plate-fins rolling forming process are carried out with FEM Deform-3D software and got the fin shaping with ideal shape. The stress state of workpiece and forces effecting on rolling tool in forming process are analyzed, and a theoretical basis for the research and application of plate-fins rolling forming method is provided.
