Forging Force Analysis of Truck Knuckle and Selection of Forging Equipment

Abstract The knuckle is difficult to form for their complex structures and great changes in cross sections during forging process. In this paper, by using of DEFORM simulation technology, analysis was made on forging force and energy in the main forging stages of typical truck knuckle. In addition, analysis has also been done on force and energy requirements and eccentric load requirements. The purpose is to select suitable press and provide design basis for establishing truck knuckle forging production line which is high efficient and stable. As a result, 8000T hot die forging press was selected to produce truck knuckles.
