摘　　要：带材在轧制过程中由于延伸不均匀就会造成浪形或瓢区等三维板形缺陷。本文采用显式动力学有限元软件ANSYS/LS-DYNA模拟了边浪带材拉伸弯曲矫直过程,分析了边浪带材的变形,得到:1)可使带钢得到有效矫直的与张应力相匹配的弯曲辊压下量;2)边浪处的延伸与平直处的延伸趋于一致,但一个弯曲单元的矫直能力不足;3)随弯曲辊的压下量增加,张应力对带材弯曲曲率的作用增大。这些结果对具有三维缺陷的带材拉弯矫直提供了有益的参考作用。Strip in rolling process produce the wave or buckles defect in the case of non-uniform extension.This paper simulate strip tension leveling using the FEM software ANSYS/LS-DYNA.analyze deformation of strip edge wave.Find:1)the bend-roller intermesh corresponding tension;2)the extension of wave and level strip is nearly same after tension levelling,but one bend unit is not enough to level strip;3)tension stress have effect to curvature obviously.The consequence will help set parameters in tension leveling process.
