Abstract [sv]

Det här examensarbetet består av en livscykelanalys av en styrsystem. Genom den studien har man försökt att fokusera och ta reda på hur en styrsystem kan påverka miljön genom sin livs längd. Alla faktorer som koldioxid utsläpp, energi-och material använding samt hur mycket detta påverkar miljön har studerats. Eftersom Livscykelanalysen brukar vara tidskrävande och detaljrat, har en enklare metod för snabbare result och analys av styrsystem valts. Den här metoden kallas för fast track LCA, det är en mindre komplicerad metod. Motivationen bakom denna studie är resurshushållning och energieffektivitet. Resultatet från denna analys skall användas för vidareutveckling av hydrualiska styrsystem, vilket skulle kunna ge möjlighet till en förbättring i de nya modellen av styrsystemet. Denna utveckling är tänkt att ske i miljövänlighets syfte. I det avslutande kapitlet tolkas och presenteras resultaten i tabeller och figurer. Baserat på dessa tolkningar kommer resultaten och utvecklingsmöjligheter att diskuterass ytterligare.Utifrån dem dras slutsatsen samt förbättringar från mijösynpunkten föreslås.

Abstract [en]

This thesis work mainly contains a fast track Life Cycle Assessment (LCA) study of a hydraulic steering gear. The study gives a picture of the hydraulic steering gear through its complete Lifecycle from an environmental point of view. The main motivations behind this study are natural resources conservation and energy efficiency. According to ISO 14040 and 14044 LCA is a complex and time consuming method, the chosen approach for LCA in this study is the Fast Track LCA. The Fast Track LCA gives results which are equally accurate and still could be achieved by taking a shorter way and applying an easier and less complicated method. The intended application of this study is to use the results for further development of the new hydraulic steering gear design, in comparison to the current one. These developments are supposed to be more environmentally friendly. In the final chapter, the findings are interpreted in tables and figures, based on these interpretations the findings are discussed further and the environmentally improvements are suggested and the conclusions are drawn.
