This paper focuses on the analysis of mechanical properties of organic-inorganic polymeric hybrid material Multimetall “Stahl 1080” containing metallic particles. This material is designed for the regeneration of used metallic parts made of steel, cast iron, or composite materials. This type of material provides a 100% contact with the surface of the filled material, attenuation of vibration loads...
The variety of possible construction solutions of machinery and technological equipment and research related to these solutions require knowledge of materials engineering, mechanics, strength of materials, electronics and mechatronics, the basics of machine construction and machine technology. It is impossible to cover such an extensive range of required information in just one publication. Therefore,...
General design rules and algorithms for supervisory systems of subtractive manufacturing processes in INDUSTRY 4.0- based manufacturing are presented in the paper. They are formulated based on the analysis of the communication standards for manufacturing integration, the idea of cyber-physical systems, and the architecture of supervisory systems operating locally. It is assumed that the monitoring...
The presented paper discusses the theoretical safety issues in complex sociotechnical systems. The traditional efforts to deal with the accidents/hazard events identification problem for complex systems seem to be insufficient, because they have tended to neglect or omitted the broader sociotechnical environment. Following this, a brief literature review in the area of sociotechnical systems modelling...
This paper presents a review of methods used for the acquisition of 3D images. A classification of such methods into contact and contactless and into active and passive methods is given. Special attention is given to show imaging methods that can be used for tasks involving product-manufacturing systems.
The article presents the results of numerical calculations of temperature distribution and thermal stress in a thermal barrier coating (TBC) applied by thermal spraying on the element of nickel superalloy. The assumed point of reference was a set of conventional TBCs made of the 8YSZ powder with the insulating layer thickness ranging between 150 μm and 300 μm. A numerical analysis was conducted to...
Research about the application of strategic foresight methods in small- and medium-sized companies (SME) is rarely discussed in literature. The aim of the paper is to investigate possible approaches to strategic foresight in SMEs as well as to present a detailed case study of its application based on an original approach. The main research methods used in his paper is a literature review of foresight...
The paper describes size effect in reference to available empirical and analytical models. The size effect of an object on strength properties was classified from 3 perspectives: statistical, geometrical, and technological. The following part of the paper identifies a verification method that has been supplemented by proprietary experimental test results obtained for a minispecimen made of aluminium...
The paper presents a determination method of the most advantageous time of preventive maintenance for milling assemblies used in the energy industry. In this particular case, we considered bowl-mill pulveriser assemblies used in power plants. Reliable operation of these assemblies is important from the point of view of continuous energy production. In addition to a reliable operation, the planned...
The article presents the studies results of corona electrodes used in industrial electrostatic precipitators (ESP). For selected types of mast electrodes, measurements of their electrical parameters have been performed. Based on the analysis of measurement data, the effect of the geometry (shape and position emission elements) on the emissivity of the discharge electrode was established. The influences...
In the work, the results of testing the actuator piston rod that corroded in the operating conditions are presented. It was found that the direct cause of the corrosion were local damages of the Cr/Ni dual-layer coating. In locations of cracking, a brittle chromium coating and deterioration was observed with the character of the sub-coating corrosion intensified by the influence of chloride ions....
The most common problems related to the operation of lifting devices installed both in residential and public buildings are presented in the article. Selected design solutions of lifting devices that are the most susceptible to wear and tear as well as the symptoms of that wear are analysed in the paper. The methods to observe the processes of progressing wear and tear are proposed based on conducted...
This article presents an experimental prototype line developed at the Institute for Sustainable Technologies - PIB in Radom for the processing of fibres in a closed water system as an element in the process of an innovative technology for the manufacture of flax fibre originating from traditional varieties of fibre plants and new varieties of flax. The paper discusses the concept of this technological...
The development of both control systems for machine fleets and computer-controlled production systems have provided companies with a wide spectrum of tools for collecting data about the operation of their machinery stocks. A vast number of companies only store historic data; however, they do not use these data to extract information with respect to improving the efficiency of their technical infrastructure...
The wearing degradation of the structure is accompanied by the increase of non-linear disturbances of the observed dynamic processes. The first of the mentioned effect can become the basis of the technical diagnostics as well as of the prognosis of the machine state change during its maintenance, if only it is possible to describe and measure such effect. In the further part of this study, it is shown...
