Hidravlična priprava za montažo stebra žerjava

Bizjak, Urban (author), Majdič, Franc (mentor), Jerman, Boris (co-mentor)

V diplomski nalogi je obravnavana montažna priprava, katera služi kot pripomoček v montažnem procesu sestave stebra gozdarskega žerjava. V začetku naloge so obravnavane faze gibanja priprave. Za vsako fazo so prikazane obremenitve, ki se pojavijo zaradi vpetega bremena. Na tej montažni pripravi, so vključene potrebne hidravlične sestavine, ki omogočajo premagovati obremenitve, ki se pojavijo, pri delovanju priprave. Za posamezne lege, so poleg analitičnih izvedeni tudi numerični preračuni. Največja izračunana notranja napetost znaša 289 MPa, kar je manj od meje plastičnosti. Obravnavan je tudi hidravlični udar v ekstremnih pogojih delovanja.

• Title: Hydraulic mouting device for assembley pillar of the crane

Abstract

In this diploma paper is presented mounting device for assembley pillar of the forest crane. In the begining of paper are seen phases of device movement. For each phase are simulated and calculated all loads which appears during the device movement. The denvelopment contains all nesseseary hydraulic components which provides full control and smooth movement. Besides analytical calculations diploma paper also contains numerical calculations and hydraulic stroke in extreme operating conditions.
