Conceptual design by using topology optimization (English)
Abstract [sv]

Den här rapporten handlar om det examensarbete som utförts mot Volvo 3P genom forskningsprojektet Viktor. Viktor är ett projekt som ska visa möjligheten med virtuell produktframtagning av gjutna komponenter. Volvo 3P är ett företag som utvecklar lastbilar. Uppgiften har varit att visa möjligheten att använda topologioptimering som ett verktyg i konstruktionsfasen. Detta har gjorts med hjälp av ett case som erhållits från Volvo 3P. Ett nytt koncept för en av deras lastbilsnav har tagits fram. Konceptet visar på högre styvhet och en lägre spänningsnivå än dagens originalnav. Konceptet hade förmodligen aldrig uppkommit om det inte hade varit för topologioptimeringen. Rapporten behandlar de steg som utförs vid en topologioptimering med programvaran Altair Hypermesh Optistruct. För att verifiera de resultat som erhållits från topologioptimeringen har koncepten analyserats i Abaqus. Rapporten tar även upp begränsningar och svårigheter som användaren kan komma att stöta på under arbetets gång.

Abstract [en]

This report documents the final project which has been performed in collaboration with Volvo 3P through the science project named Viktor. Viktor is a project which will show the opportunities with virtual product development of cast iron products. Volvo 3P is a company which among other things develops trucks. The task has been to show opportunities with topology optimization as a tool in the construction phase. This has been done with help from a case that has been received from Volvo 3P. A new concept for one of their hubs has been developed. The concept shows greater stiffness and a lower stresses compared to the original hub. The concept would probably not have been developed without using topology optimization. This report concerns the multiple steps which are used to perform optimization with the computer program Altair Hypermesh Optistruct. To verify the results which has been received from the topology optimization Abaqus has been used as a FE-tool. The report also contains the limits and difficulties which can occur during the process
