Abstract Scope |
Car designers must achieve high levels of crash safety performance while also minimising weight to reduce the amount of energy consumed by driving. To achieve these contradictory goals the latest car body designs are using aluminium closures, aluminium bodysides, large aluminium die castings, hot formed high strength aluminium alloys, dual phase high strength steels, and hot stamped press hardened steels. There is also a desire for using narrower flanges to improve driver visibility by reducing pillar sizes plus reduce the amount of material required to gain cost and weight savings. These trends are driving advances in mechanical fastening technologies. This presentation will give an overview of the latest developments in Self-Pierce Riveting technologies, showing some examples of how the latest rivet technologies are being utilised by car designers to achieve their design goals. |
