以法兰长杆件法兰部分的冷摆辗成形工艺为研究对象，建立了三维刚塑性有限元分析模型，对该工艺的成形过程进行了模拟研究，得到了变形过程中工件上的应力应变分布、应变速率分布以及上述场量的变化过程，为进一步掌握摆动辗压变形机理、制订合理的工艺参数提供了理论依据。
Taking the cold swing forming process of the flange part of the flange as the research object, a three-dimensional rigid-plastic finite element analysis model was established and the forming process of the process was simulated. The stress and strain on the workpiece during the deformation process were obtained Distribution and strain rate distribution as well as the change of the above-mentioned field quantities provide theoretical basis for further grasping the rolling deformation mechanism and formulating reasonable process parameters.
