The Purpose of the project was to find the reasons of cracking in ferite core RM7 produced by Magma Kolektor. The reason of ferite cores cracking was found and the deficiencies were removed, which stopped customer complaints and normalised the production process.
F.05 Ability to launch new technological development cycle
COBISS.SI-ID: 9617947The propose of the project was to improve skiing perfomace of Slovenian skii producer ELAN. The measurement of lift forces of ski tips were done in the wind channel for different configurations. The mechanism of aerodynamic force influence on the ski was determined and configurations with better aerodinamical properties were selected.
F.06 Development of a new product
COBISS.SI-ID: 9617691This paper presents axisymmetric simulation of a rocket nozzle for different ratios of nozzle inlet and ambient pressure. The finite-element method was used for the simulation of a transient, turbulent flow of compressible, viscous and adiabatic fluid. The gradient method for mesh refinement and pressure gradient as a condition for refinement was used. The results of the numerical simulations were in agreement with experiments in literature.
F.05 Ability to launch new technological development cycle
COBISS.SI-ID: 10178075This work deals with thickness optimization of a circular annular plate at buckling. The plate is loaded with uniform, axially symmetric, in-plane loads on the inner and outer edge. The variable thickness of the plate is approximated by a function of radial coordinates and design variables. An optimization problem is defined to find optimal sets of design variables which maximize buckling loads at constant weight/volume of the plate.
F.04 Increase of the technological level
