Application of geometry model updating method in FEM analysis of plane pattern of plate
The plate multipass rolling process with plane pattern control was analyzed with updated geometry method on the platform software LS-DYNA. After one pass was finished, simulation model of the next pass was built and the rolling geometry model was updated by changing roll gap, material attribute, boundary conditions and loads. By comparing the simulated results with measured data, it is found that good agreement is achieved, the updated geometry method can be used to analyze the plate plane pattern in plate rolling process and a new method of using simple pass rolling model can be used to solve multipass rolling problems.
