Abstract：

The geometry model of slab sizing press was established by SolidWorks, and the whole process of slab sizing press was simulated and analyzed by the nonlinear large deformation finite element analysis software ANSYS/LS-DYNA. The variation regularity of the side impact force and stress state in different lateral regions was researched, and the simulation results were compared with the same size slabs under different lateral pressure widths and the different size slabs under the same lateral pressure width. The results show that the non-steady deformation region exists on the slab head and tail, while the central slab is the steady deformation region. The slab impact force, stress and the dog bone height increase with the rise of lateral pressure width, the thickness of the slab is proportional to the impact force and the height of dog bone, while the width of the slab is inversely proportional to the impact force and dog bone height. Therefore, a reasonable selection of slab width and the slab specifications as well as the strict control the size of impact force which can not only improve the quality of the slab and the service life of the equipment, but also provide a reference for the production of the customized slab regulations.
