Automated Dimensioning of Promas MK. II Hub Cap

University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

Abstract: The studyis a part of the development of the new dimensioning standard fora hub cap,Hub Cap MK II.A goal with this study wasto obtain a dimensioningtool which willeliminate current issuesand validate its trustworthiness with FEA simulations.This is executed togetherwith the purpose of giving an increased understanding of the hub cap’s structural behavior in its operating environment.The hub cap’s general structural mechanics is studied with Euler-Bernoulli beam theoryand is modeled as a cantilever beam. Ananalysisoffatigue in weldsand how much stress theycan withstandis performed with S-N diagram. The clamping force in the bolted jointholding the hub cap in its positionis studied in this paper. Together, a theoretical maximum length of the hub cap could be calculatedto preventfailing.A total of 12 equations relating the maximum length
