Abstract [sv]

Vibrationsmätning är inget nytt fenomen men många företag anser sig ändå skeptiskatill den abstrakta metoden. Samma skepticism finns inte vid ett läkarbesök där doktornlyssnar efter oljud med sitt stetoskop, ändå är likheterna slående. Med dagens teknikär det möjligt att diagnostisera en maskins olika beståndsdelar efter skador genom attanalysera det unika vibrationsmönster de bidrar med.

Detta arbete syftar att minska denna barriär med hjälp av en introduktion till de olikabegrepp och val som finns inom vibrationsteknisk analys som hjälpmedel för underhåll.Slutligen presenteras en implementeringsmall där ekonomi och tillgänglighet anses varamest vitala inför framtida beslut.

Abstract [en]

Even though vibration measurement is not a new phenomenon, many businesses stillremain sceptical towards the somewhat abstract method. Same scepticism does not existwhen you visit the doctor and he uses his stethoscope to listen after abnormalities inthe sound pattern, even though the similarities are striking. With todays technology it ispossible to diagnose a machine’s different parts in search for damages by analysing theunique vibrationpatterns they provide.

This study aims to close this gap with the help off an introduction to the different termsand choices that exist in vibration analysis as a tool in preventive maintenance and finallyto present guidelines for implementation where economy and availability is consideredmost pivotal for future decisions.
