Study on influence of roll speed upon the stress and strain of large-sized shaft in cross wedge rolling

轧辊转速是关系到楔横轧大型轴类件成型质量和效率的重要技术参数之一,本文采用ANSYS/LS-DYNA有限元分析软件,对楔横轧大型轴类件进行模拟,分析了轧辊转速对楔横轧大型轴类零件应力应变影响规律,为楔横轧大型轴类件确定合理的轧制速度、实现大型轴类件楔横轧经济化生产提供理论依据。

Roll speed is one of the major technical parameters for rolling large - sized shaft using cross wedge rolling method. It concerns the forming quality and productivity of the components. In this paper, by using finite software of ANSYS/LS - DYNA, the cross wedge rolling process for forming large - sized shaft parts is simulated. The influence of the roll speed upon the stress and strain of large - sized shaft in cross wedge rolling is analyzed. The results can provide a theoretical foundation for selecting reasonable rolling speed and accomplishing economic production of large - sized shaft with cross wedge rolling method.
