In order to investigate the deformation behavior of a plate during a vertical-horizontal rolling process, a thermo-mechanical coupling analysis is carried out by three-dimensional (3-D) rigid-plastic FEM to simulate the process. The metal flow and the shape evolution of the plate are focused during this investigation. The thickness and the width of the plate agree well with the measured values.

Roll Gap

Using rigid-plastic finite element DEFORMTM 2D software, this study simulates the plastic deformation of complex sheets at the roll gap during the sheet rolling process. Specifically, the study addresses the deformation of complex sheets containing inclusion defects. Under various rolling conditions, the present numerical analysis investigates the damage factor distributions, the void length at the front and rear of the inclusion, the deformation mechanisms, and the stress-strain distributions around the inclusion. The relative influences of the thickness reduction, the roll radii, and the friction factors on the void length at the front and rear of the inclusion, respectively, are systematically examined. Additionally, the correlation between the front and rear void lengths and a series of damage factors is explored. The simulation results appear to verify the suitability of the DEFORMTM 2D software for modeling the rolling of complex sheets containing inclusions.

H Beam

In order to research the hot rolling process of large H-beam, the thermal-mechanical coupling analysis and big distortion theory are used to simulate the whole X-H rolling process of HN900x300 by ABAQUS, in which the re-meshing technique is taken into simulation to increase the accuracy. Based on the simulation results, the stress and deflection of the roller as well as the metal flowing law and temperature field of workpiece are discussed emphatically. The results clearly show that the roller is subjected to alternating shear force and compressive stresses of three directions, and the metal of flange tends to flow from outside to inside. The simulation results are compared with the measuring results, which proves the correctness of simulation.

Vibration Parameters

Vibration rotary forging is a complex precision forming process. In the forming process, the addition of the vibration make the boundary condition and the friction condition of the gear blank and the mould changed with the rotation of the head, which lead the forming process of the spur bevel gears become more complicated. Using the rigid-plastic finite element method to study the metal flow law and the stress distribution of the gear blank during the forming process of the spur bevel gears. Using the DEFORM-3D finite element analysis software to simulate and analysis the forming process of the spur bevel gear, in order to get the forming law of the bevel gear during the different type of the vibration parameters.
