    This paper is focused on numerical analysis of a hydraulic arm for use on a light goods vehicle. The designed arm is used for loading and manipulation with load up to 300 kg. Its load capacity depends on the light goods vehicle to be placed on. Great operability of this mechanism predetermines its wide application, e.g. in construction, transport, business etc. Firstly, analytical calculations of the forces, moments and reactions are introduced. Further, locations and values of the maximum stress in the structure of the designed hydraulic arm are calculated using the FEM software. These results determine the relevant data necessary for correct design functioning of the machine. After carrying out all the analyses and calculations we will be able to determine the safe use of the designed handling machine and put it into operation.

    The development of microelectronics intervened greatly in the automotive industry, therefore this fact cannot be ignored in the education. In today’s teaching absent methods, special classrooms and didactic tool, that allow to know the operating principle, processes understanding and also diagnostics of vehicle electronic systems. The project, which is realising at the University of Žilina intended for the modern education of several study programs is presented in this paper.

    This project will influence on professional qualifications of project investigators. They will improve their knowledge by means of professional training. New knowledge they will transfer subsequently in the education.

    The strategic goal of the project is “Reconcile the needs of the knowledge society and the labour market in higher education in the field of automotive technology”.

  • DETECTION OF THE FATIGUE OPERATING LIFE OF THE WELDED JOINT OF AN ALUMINIUM ALMGSI07 ALLOY AT UNIAXIAL TORSION STRESS OF THE SPECIMENS

    The paper deals with an experimental measurement of the fatigue operating life of a specimen from the aluminium AlMgSi07 alloy on a built testing equipment, into which the welded joint was implemented. An importance of the measurement is in a comparison of achieved results with the same material, which was not subjected to welding. The result of the research is verification of the influence of welding on the fatigue operating life of the concrete material at torsion stress.

    The paper deals with a design of a regenerator of Stirling engine with unconventional mechanism of engine FIK. The final design of the regenerator is based on previous simulations of flowing of a working fluid, created in software Fluent. The paper presents basic requirements to be followed in the design of the regenerator. The contribution also contains a dimensional computation of the regenerator, which describes basic procedures and boundary conditions in the computation of the designed shape of the regenerator.
