TECHNICAL STUDY OF HIGH STRENGTH STEEL IN STRUCTURAL ELEMENTS IN VEHICLES

Forming is the main problem when working with steel in sheet form. The friction between the working tool and the workpiece is very important, and a precise knowledge of friction in these fields for proper process design, tool design, surface quality and process control training is needed. Forming causes tangential forces, which act between the die and the workpiece, in a resisting relative movement between the two surfaces. The frictional force can be easily varied with adequate lubrication or altering the tool or workpiece surface roughness. This research is carried out to study these phenomena to decrease manufacturing costs, and improve production and forming. The material tested in this study is steel used in the automotive industry, more specifically in the manufacturing of car chassis.
