The effect of restraints type on the generated stresses in gantry crane beam

Abstract

Abstract. This paper includes an analysis of the mechanical phenomena in the gantry crane beam, because the cranes are currently one of the most common devices for the transporting loads. Designing modern mechanical structures is a complex task that requires the use of appropriate tools. Such a modern tool is the numerical simulation, which uses different numerical methods. One of the best known methods is the finite element method, also used here. Simulations are limited to analysis of the strength of the gantry crane beam that was the loaded of the force load movement along its length. The numerical analysis was made to the gantry crane beam which crosssection was an I-beam and ends were fixed in different ways. As the result of numerical calculations, the stresses and displacements of the structure of gantry were obtained. The influence of the restraints type and changing the loading force position on generate the Huber-Misses stress in the gantry crane beam was estimated. The aim was to ensure that the maximum equivalent stress generated in the gantry crane beam was less than the strength of material, because then the construction is safe.

“…Extensive research is carried out to develop strategies for vibration damping [7]. The influence of the restraints type and changing the loading force position on the generated Huber-Misses stress in the gantry crane beam was estimated in paper [8]. In papers [9] and [10], deflection values occurring in the main girder of a portal crane at various payloads were investigated theoretically, numerically and experimentally.…”
