H型钢热轧过程中残余应力有限元模拟

FINITE ELEMENT STIMULATION OF RESIDUAL STRESS DURING H-BEAM HOT ROLLED PROCESS

在热轧H型钢的生产过程中,由于H型钢断面的复杂性,导致在长度方向上翼缘和腹板之间形成了一定的残余应力,严重影响了H型钢的性能。本文通过采用ANSYS软件对热轧H型钢的热轧过程进行模拟,定量的分析了残余应力数值的大小。

During H-beam rolling,the complexity of H-beam section causes the residual stress formed between the web and flange,which greatly decreased the property of H-beam.The paper numerically analyses the residual stress during H-beam hot rolling with ANSYS software.
