Bucket wheel excavator cutting tooth stress and deformation analysis during operation using Finite Elements Method (FEM)
(Wydawnictwa AGH, 2018) Kertész Brînaş, Ildiko; Rebedea, Narcis Ionel; Oltean, Ilie Luciano
In the case of bucket wheel excavators, the cutting process is influenced by the forces opposing the working elements and cutting tools. These forces determine the choice of machines and their parameters as well as the operating method [1, 2]. Studies conducted on the failure causes of mechanical parts show that the cutting and loading systems cause the highest rate of failure - about 32% of all recorded mechanical failures [3]. In this paper, we will use the Finite Element Method (FEM) to analyze the deformations and stresses acting on the cutting teeth mounted on the rotor of BWEs. For this, Solid-Works® software was used, both as a CAD tool to design the teeth as well as to model and simulate the phenomena.

Naprężenia, odkształcenia i konwergencje na różnych głębokościach kopalń soli, studium modelowe dla chodnika w górotworze solnym
(Wydawnictwa AGH, 2009) Maj, Agnieszka
The paper presents the influence of depth on stresses and strains around the gallery in salt rock mass. The method of taking the values of initial stresses corresponding to the state of stress in salt rock mass for analyses is described. The distributions of stress, strain and convergence of gallery are calculated for elastic-viscous medium using Finite Element Method. The results of this paper may be used for recognition of the stress conditions in salt rock mass and estimation of viscous properties of rock mass on the basis of the convergence measurements at various depths.
