ABSTRACT The need to fabricate sheet components with large thickness, size and complex curvature in the shipbuilding, transportation, and defense industries is increasing. Traditional methods such as stroke stamping, bending, forming, local heating, manual forming on universal press equipment, then re-welding [1, 2, 3], so productivity as well as product quality is usually not high. In order to improve the efficiency in shaping the sheet components with complex curvature, technicians research and apply modern technologies that allow fast and precise shaping such as pressing, rolling, continuous local shaping on digital control devices. This article will present the research results and apply the numerical simulation results to the experimental forming of the sample by rolling technology. These research results will be applied in ship hull manufacturing industry in shipyards in Vietnam. Keywords: Deformation; rolling; numerical simulation; large plate forming. |
