Abstract [sv]

Examensarbete är den avslutande delen i utbildningen till Civilingenjör, arbetets omfattning är 20 poäng av de totalt 180 poäng som utgör utbildningen. Examensarbetet har utförts på Sapa Automotive i Vetlanda.Syftet med examensarbetet har varit att ta fram en utvecklingsmetod som Sapa Automotive kan använda sig av vid sina utvecklingsprojekt, gällande själva konstruktionsarbetet, av takräcken till bilindustrin. Sapa Automotive är specialiserade inom produktutveckling och tillverkning av komponenter och system baserade på strängpressade aluminiumprofiler för fordonsindustrin. En av Sapa Automotives affärsidéer är erbjuda kunderna utveckling av takräck till personbilar. I dessa projekt tar Sapa Automotive på sig att utifrån givna designförutsättning utveckla de ingående komponenterna och sedan industrialisera den färdiga konstruktionen. Resultatet av examensarbetet var en manual som Sapa Automotive kan använda sig av vid kommande utvecklingsprojekt. Manualen innehåller CAD-metodik, dokumentationsmallar, konstruktionsriktlinjer och toleranskedjeblankett. Och även en beskrivning på hur konstruktören själv kan utföra sina egna FEM-beräkningar direkt i CAD-verktyget.

Abstract [en]

The master thesis is the final part of the Master of Science education, the thesis extent 20 points of the total 180 that the educations contains of. This master thesis has been done at Sapa Automotive in Vetlanda. The aim with the thesis was to develop a method that describes how Sapa Automotive should work in their development project, concerning the design work, of roof rails to the automotive industry. Sapa Autototive is specialized within product development and manufacturing of components containing extruded aluminum profiles to the automotive industry. One of the business areas is design and manufacturing of roof rails for passenger cars. In this projects Sapa Automotive handles the design of the parts that the roof rail is build and they also handles the industrialization of the finished design. The result of the master thesis was a guidebook that Sapa Automotive could use in their upcoming development project. The guidebook contains CAD-methods, documentation forms, design guidelines and tolerance chain form. And also descriptions on how the designer can do his/her own FEA-calculations in the CAD-program.
