| 摘 要： | H型钢辊式矫直过程及矫直后的残余应力对其承载能力有很大影响,传统上以残余几何形态评价矫直效果存在一定不足.基于弹塑性理论,对辊式矫直过程中H型钢断面上弹性核高度和残余应力进行了理论研究,推导出了相关解析公式,结合实例计算及仿真,验证了解析公式的正确性,对现场工艺参数的制定提供了理论依据.

| Abstract: | The residual stress of H-beam brought in roller straightening is very influential on the carrying capacity of H-beam.It is not perfect to appraise the straightening effect only by residual curvature traditionally.In this paper,based on elastic-plastic theory,elastic core height of section and residual stress of H-beam in roller straightening are studied.Correlative formulae are deduced.According to the simulation of examples,it is shown that the formulae are correct.The conclusions of this paper are importa... |
