Numerical simulation of spinning forming of A356 aluminum alloy hub using dual spinning rollers

Abstract A finite element model of one-pass forming of an A356 aluminum alloy hub using dual spinning rollers was established, and the effectiveness of the finite element model was verified through experiment. The established finite element model was used to study the influence of the feed rate, the spindle speed, the axial distance of the two spinning rollers, and the friction coefficient on the forming quality of the hub. The result shows that a good forming quality could be obtained when the feed rate is 4 mm/s, the spindle speed is 220 rpm, the axial distance between the two spinning rollers is 3 mm or 7 mm, and the friction coefficient is 0.2. The simulation results can provide a reference for actual spinning production processes.
