摘要：

A finite element model of high-strength rectangular section steel tube in rotary-draw bending is established to study the stress and strain in the bending process. Based on control variate method, this paper analyzes the influence laws of three geometric parameters on rotary-draw bending. The results show that bending radius is the most important factor, forming property increases significantly with the increase of bending radius, the trends of cracking and wrinkling are all decreased. The thickness of wall has influence on the strain of in wall, thinner tube may cause crack and wrinkle. Fillet radius has no effect on ektexine, the strain of in wall decreases slightly with the increase of fillet radius. © (2014) Trans Tech Publications, Switzerland.
