摘    要:轧制力是楔横轧成形大型轴类件的重要技术参数之一。文章采用ANSYS/LS-DYNA3D有限元软件对大型轴类件的楔横轧成形进行数值模拟,分析轧制力随工艺参数和轧件直径变化的规律,通过轧制实验验证表明,有限元模拟具有良好的可靠性。该文对于楔横轧大型轴类件轧制力规律的研究结果,为设计大型楔横轧机确定力能参数,实现大型轴类零件的楔横轧经济化生产,提供了理论依据。

关 键 词:楔横轧  大型轴类件  轧制力

Abstract:Rolling force is one of important technological parameters in forming large-sized shaft-part by the cross wedge rolling.By using Finite Element Method ANSYS/LS-DYNA3D software,the cross wedge rolling process of forming large-sized shaft-part is simulated.It is also to be analyzed that the varying rule of rolling force with technological parameters and part's diameter changing.Through experimental verification,the result shows that Finite Element Method simulation has great reliability.The paper for the result of varying rule of rolling force can provide theoretical foundation with setting parameters of force and energy for designing large-sized cross wedge rolling mill and achieving economic production of large-sized shaft-part by cross wedge rolling.
Keywords:cross wedge rolling  large-sized shaft-part  rolling force
