Theoretical Research of Residual Stress on H-Beam Roller Straightening
The residual stress of H-beam brought on roller straightening is very influential on 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 on roller straightening are studied.Correlative formulae are deduced.Examples and simulation results show that the formulae are correct.The conclusions of this paper are important for the establishment of straightening technological parameters.
