Abstract
In the automotive industry, aluminum is widely used to reduce the vehicle weight. Aluminum curved extruded components are used for the design of frame parts. This study investigates the curvature extrusion process to produce the aluminum curved suspension arm. In the curvature extrusion process, the bending process is simultaneously carried out with the extrusion process. Firstly, porthole extrusion was investigated by using FE analysis to produce aluminum suspension arm. And then the bending process condition was determined to produce the final suspension arm with the required curvature. In this research, the guide roll movement causes the bending of extruded product. The moving distance and velocity of guide roll were controlled to meet the required curvature of suspension arm. Finally, the curved suspension arm was manufactured by the curvature extrusion experiment under the proposed curvature extrusion condition.
