Analysis of Rolling Force and Torque in Asymmetrical Rolling Process by FEM Method abstract

Today, the rolled products, i.e. sheet, plate and foil is used in various applications, including platforms, heat exchangers, automobile structures, mast, tank, boat hulls and aircraft fuselage. In this paper, simulation of asymmetric cold rolling is presented by using explicit analysis procedure proposed to calculate the rolling force and rolling torque in asymmetrical sheet rolling where the work piece radii, their speeds may be different. A two dimensional explicit dynamic finite element model with adaptive meshing technique has been employed to simulate asymmetrical condition are here due to different roll radii. To validate the simulation, results of simulation and experiment are compared together appropriately. Effects of asymmetry due to roll radii ratio and speed ratio mismatch on rolling force and rolling torque are discussed. Finally, it is shown that by increasing radii and speed ratio, rolling torque is decreased
