摘要：通过显式动力学有限元法，采用ANSYS/LS-DYNA软件，对4mm厚304奥氏体不锈钢薄板带冷轧过程进行模拟分析。研究表明，冷轧过程中施加前后张力对薄板带轧后板形有一定的影响，本模拟中，前张力为30MPa，后张力为17MPa时，应力值与应变值波动较平缓，变形比较均匀，板形良好。此外，增大前后张力均会导致边部减薄量减少，而随着摩擦系数的增大，轧件的边部减薄量增大。

Abstract: A computer simulation analysis was carried out for the 4-mm thin cold rolling process of 304 austenite stainless steel strip by means of the explicit dynamic finite element method and the ANSYS/LS-DYNA software. The research indicates that the value of the tension has a certain effect on the profile shape. In this simulation, when the forward tension is 30 MPa and the backward tension is 17 MPa, the fluctuation of the stress value and the strain value is relatively smooth, with uniform deformation and good profile shape for the strip. Furthermore, the amount of edge drop will reduce if tension increases. However, the rolled edge-drop volume will increase with the increase of the friction coefficient.
