Abstract:Magistrsko delo obsega dinamično analizo ladijskega razkladalca s štirivrvnim grabilcem. Portalni žerjav za premikanje grabilca uporablja kompleksen vrvni mehanizem. Cilj magistrskega dela je bil, da se v programu MSC Adams ustvari parametričen model vrvnega mehanizma in se analizira delovni cikel ter dinamične lastnosti komponent žerjava. Dinamični model je bil krmiljen s tremi elektromotorji. Odziv vrvnega sistema je bil pravilen, saj so grabilec in mački dosegli njihove ciljne hitrosti. Grabilec je na nadzorovan način transportiral premog in uspešno opravil en delovni cikel. Numerični rezultati sil v vrveh, reakcij v vrvenicah in navorov ter moči elektromotorjev so se dobro ujemali z analitičnim preračunom. Do večjih razlik je prišlo zaradi prevelikih poenostavitev pri analitičnem preračunu. Izkazalo se je, da je računalniška dinamika sistemov teles (ang. Multibody Dynamics) ustrezno orodje za simulacijo dinamike jeklenih vrvi, saj je bilo mogoče zajeti vse pomembnejše pojave in vplive na vrvni mehanizem.

Title:Dynamic analysis of a ship unloader with a four-rope grab
Abstract:The master’s thesis encompasses the dynamic analysis of a ship unloader with a four-rope grab. The portal crane uses a complex rope mechanism to operate the grab. The goal of the thesis was to create a parametric model of the wire rope mechanism in MSC Adams and to analyze the unloading cycle and the dynamic properties of the crane’s components. The multibody dynamics model was driven by three electric motors. The response of the rope mechanism was correctly predicted, as the grab and trolleys achieved their target velocities. The grab handled coal in a controlled manner and successfully completed an unloading cycle. The numerical results of wire rope forces, reactions of sheaves, electric motor torque and power matched the analytical results. Larger differences in the comparison were due to the assumptions used in the analytical calculations. One of the main findings of the study was that Multibody Dynamics is a suitable tool for dynamic wire rope simulations, as all the most important interactions and phenomena were accounted for in the simulation.
