| Abstract: | Nonlinear FEA technique is used to simulate the based on LS/DYNA module of ANSYS. The characteristics whole process of two-roll straightening dynamically of stress and strain distribution during the two-roll straightener were obtained by the finite element analysis, and the quality and accuracy of straightening in different angles were analyzed to guide on-site engineering personnel to quickly adjust straightening rol! angle. The straighte-ning forces and the guide plate forces have been calculated, which will provide theoretical basis for the development of new equipment. |
