Abstract [en]

The quest to diversify the renewable energy producing systems has led to the development of wave energy converters. To get to a viable commercial wave energy converter system it is very crucial to have a levelized cost to energy for the system. This is done driving forward the system level optimization and upgradation for the whole wave energy converter.

In this thesis, the focus was the support for the development of a full scaled composite pretension cylinder. Different predictive models were identified and studied to characterize the effects due to the cyclic reciprocating contacts on the composite pretension cylinder. The results of which, gave an early input to move forward towards more accurate testing leading to the development of a test rig. The test rig once developed could provide with the long term required data so that the actual composite pretension cylinder be designed and integrated onto the wave energy converter.

Abstract [sv]

Strävan efter att diversifiera de system som producerar förnybar energi har lett till utvecklingen av vågenergiomvandlare. För att komma till ett livskraftigt kommersiellt vågenergiomvandlingssystem är det mycket viktigt att ha en nivåiserad energikostnad för systemet. Detta görs för att förbättra systemnivåoptimeringen och uppgraderingen för hela vågenergiomvandlaren.

I denna avhandling var fokus stödet för utvecklingen av en fullskalad komposit förspänningscylinder. Olika prediktiva modeller identifierades och studerades för att karakterisera effekterna på grund av de cykliska fram- och återgående kontakterna på den sammansatta förspänningscylindern. Resultaten gav en tidig input för att gå vidare mot mer exakta tester, vilket ledde till utvecklingen av en testrigg. Den testrigg som en gång utvecklats kan ge långsiktigt erforderliga data så att den faktiska sammansatta förspänningscylindern kan utformas och integreras i vågenergiomvandlaren.
