    Prediction of the plastic component parts durability with use of a drop test simulation
    (2011) Warzecha, Mariusz; Młyniec, Andrzej; Uhl, Tadeusz
    This paper describes the method of performance of a drop test simulation for elements made of polymeric materials. Possibilities to use material models were described and material model choices were shown. Material tests needed to obtain material model parameters were presented and the results of analysis and measurement data were shown. As an example a drop test of the housing of a car electrical box made of Polypropylene with 20% Talc filler (PPTD20), have been simulated in ABAQUS/Explicit and results have been compared with data registered by a video camera system during the real drop test of this housing.

    Study of functional performance improvements for cutting teeth mounted on bucket wheel excavators operating in Oltenia coal basin - Romania
    (Wydawnictwa AGH, 2018) Popescu, Florin Dumitru; Radu, Sorin Mihai; Andraş, Andrei
    The values of the resultant forces acting on the cutting teeth of BWEs can either be calculated or determined using experimental methods. Based on this, the position and parameters of the working organs during the cutting process are designed and built. The stresses and deformations of the teeth during the cutting process are influenced by their positioning on the excavator bucket, which is determined by the fitting mode of the teeth. In this paper, the stresses and deformations in the case of an existing tooth holder are analysed and a new type of tooth holder is proposed, using SolidWorks® software for this analysis.
