| Abstract: | To get the deformation behavior and the temperature field of piece, commercial FEM program LSDYNA has been used to analyze the whole rolling process of 1250mm- 20mm strip and the approach is based on three dimensional thermal mechanical coupled finite element method. The rolling process is divided into some unites for calculation. The construction of model, material parameters, boundary conditions and loading in the simulation are expatiated in details. The simulation results coincide well with the measured temperature values. This approach gives the possibility to obtain the three dimensional deformations and temperature field of piece in whole rolling process. |
