This work deals with dynamic properties of a ram of gantry machine tool from firm TYC Strojírny s.r.o. Respectively by casting of the ram determining its own nature frequencies and its own waveforms. The work contains experimental measurement and its results, and transferring this&...

We can see changes in technological, socioeconomic and cultural features caused by industrial revolutions. Among the technological features belongs also maintenance management. The approach towards equipment maintenance has changed throughout the revolutions from reactive towards predictive. Instead of fix...

The contribution describes a new algorithm of thermographic evaluation of pulse thermography. The principle is in a time transformation of a thermographic sequence. The technique provides result in one image instead of series of images as standard algorithms do (FFT, TSR, derivation). T...

The article is focused on the thermal behaviour of a spindle of a milling centre. This is a typical problem of high precision machines, which produce heat as a negative implication of the produce activity. Thermal loading influents productivity and precision of a milling centr...

The purpose of this work is to explain the choice of materials and fluoride salts for Molten Salt Reactors. The article describes the problem of corrosion in these reactors and the possibilities of its mitigation. There are usable materials for MSR and their cover layer s...

The paper describes the research activities on the VT-400 test air turbine. Device VT-400 is part of the experimental research on Power System Engineering Department. The paper provides basic information about the current state of the test rig, describes the used measurement techniques&...

The main goal of this work is to analyze ergonomic models of cross-country and trekking poles and to present suggestions for improvement of existing parameters. The aim is to maximize comfort while eliminating adverse effects on users. Partial goals of the work are as follows:...

A low pressure superheated hydrogen steam system has been used to accelerate the oxidation kinetics while keeping the electrochemical conditions similar to those of the primary water in a pressurized water reactor. A special corrosion apparatus was built in cooperation with University o...

The paper is focused on cutting tool testing. The cutting tools have a different helix and rake angle in the groove. The main comparative parameter was the cutting tool durability, which was evaluated by wear on the flank surface of cutting edge. The limit cutting tool&#x...

In this paper a new simulation method of Airbag test is introduced. The method is aimed at validation of A-Pillar trim. The FE simulation is based on explicit solver using Abaqus software. Thanks to the simulation potential problems were discovered and non-beneficial design variant...

This work is focused on grinding Inconel 718, which belongs to the group of hard-to-machine materials. The aim of this work was to verify a galvanic grinding wheel when the surface roughness was the main criterion. This type of grinding wheel will be used for grinding...

The aim of this article is to introduce to the reader problems which is connected with processing of WC-Co composite material by the technology known as SLM (Selective Laser Melting Technology). The biggest problem associated with the material processing process is the porosity of&...
