Inflection moment calculation and resilience analysis of roller straightening
Based on elastic-plasticity theory and appropriate mathematical model, stress and strain of steel bars in arbitrary bending state during the process of straightening is analyzed to deduce original ratio of curvature, the included angle between original bending plane and inflection plane and inflecti...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Based on elastic-plasticity theory and appropriate mathematical model, stress and strain of steel bars in arbitrary bending state during the process of straightening is analyzed to deduce original ratio of curvature, the included angle between original bending plane and inflection plane and inflection moment. Corresponding resilience is analyzed to come to a conclusion that rebound plane turn around neutral axis to inflection plane. Roller system configuration of three-roller equal curvature of hot rolled ribbed steel bar is proposed to solve the problem that the steel bar rotate around its own axis during the straightening course, so comprehensive circle straightening is accomplished and straightening precision is improved. |
