Trdnostna analiza ogrodja motornega kolesa pri vožnji čez hitrostno oviro : diplomska naloga visokošolskega strokovnega študijskega programa I. stopnje strojništvoŠkrbec, JanCilj diplomskega dela je določitev napetosti in deformacij, ki se pojavijo na ogrodju motornega kolesa pri vožnji čez hitrostno oviro. Ker je testiranje drago in zamudno, v industriji vse večjo vlogo ... prevzemajo t.i. virtualni trdnostni testi (ang. Virtual Durability Tests). Eden izmed takšnih testov je tudi vožnja čez oviro (ang. Speed Bump Test), kjer simuliramo vožnjo vozila čez hitrostno oviro pri določeni hitrosti. Izhodišče za trdnostno analizo je dinamski sistem togih teles, ki nam poda informacijo o obremenitvah posameznih elementov. Ključni podatek za dinamično simulacijo sistema so karakteristike vzmetenja in geometrija ogrodja, ki so bili določeni in modelirani na osnovi meritev. Predpostavljen je bil linearni potek togostne karakterisike, za izračun koeficienta dušenja pa je bila vzmet obravnavana kot enostaven sistem masa-vzmet-dušilka. Rezultati dinamične analize predstavljajo robne pogoje numeričnega modela. Trdnostna analiza je bila narejena v programskem okolju Ansys z uporabo metode končnih elementov. Ugotovljeno je bilo, da so napetosti in deformacije znotraj elastičnega območja, največje vrednosti pa dosegajo na pregibih (kolenih) cevastih profilov in bočnih ojačitvenih rebrih. Izsledki analize bodo uporabljeni kot vodilo pri snovanju ogrodja motornega kolesa iz umetnih mas.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
