Failure analysis of the hinge-lever mould oscillator bearings of the continuous casting machine

Abstract: The results are considered of the investigations into the reasons and mechanisms of wear of the hinge-lever tilting mechanism bearings of the continuous billet casting machine mold operating in the rolling motion mode. The types of defects of the outer and inner rings of the bearing are determined, as well as their shape and relative position. The optical and electron- microscopic analysis of the surface of the defect is performed. It is established that the static and dynamic loading parameters have a significant effect on the mechanisms of friction and wear, as well as on the formation of dents in the bearing races. The results obtained allow assessing the reasons for wear of the hinge-lever tilting mechanism bearings, and laying the ground for the development of the technique for their elimination or minimization.

Morphology of periodical structures on surface of steel 15Kh13MF after the nanosecond laser irradiation accompanied by generation of shock waves

Abstract: The influence of processing parameters on the morphology of periodical structures on surface of steel 15Kh13MF after the nanosecond laser irradiation are discussed and analyzed. Modification of microstructure, surface morphology, and hardness by laser treatment is discussed.

Improvement of the organizational-economic mechanism of resource-saving at the machine building enterprise

Abstract: The characteristic of the resource-saving at the machine-building enterprise has been presented. The complexity and system of the resource-saving control, as well as reasonableness of the development of the efficient organizational economic resource-saving mechanism have been interpreted. It was testified that the basis of the successful activity strategy in the resource-saving at the local machine-building enterprises is the efficient application of the available resources according to the requirement of the manufacturing products. Efficiency of such control can result from the proper application of the resourcenomy levers as a new science. Innovation chain of investigation of the resource-saving control problems from the point of view of resourcenomy has been proposed. Determination of the most efficient ways of setting up the organizational economic mechanism of resource-saving basing on the qualitative and quantitative factors of the resources application, using the resourcenomy techniques and taking into account the possibility to provide the enterprise with technologies, staff, control system, as well as the influence of each of the factors of the outside and inside environment of the enterprise, has been presented.

Analysis of the interaction of participants freight forwarding system

Abstract: Main goal of this work is the analysis of the interaction of participants of freight forwarding activities. Research methods included analysis of scientific literature, theory of systems and systems analysis, methods of induction and deduction. As sources of information used and applied work of fundamental importance known foreign and local scientists and regulatory and legislative documents of Ukraine for the state transport policy. In the article the basic interactions of participants of freight forwarding activities. Classified components freight forwarding services. Assign the concept freight forwarding system and its aim. Established element and forms of cooperation in the freight forwarding system. The main task of forwarding companies are organizing, coordinating and ensuring the delivery from shipper to consignee. Freight forwarding company responsible for the timely delivery of the goods on the condition of preservation of the quantity and quality specified time conditions. Currently used methods are uneffective decision-making, leading to losses. These circumstances require improvement methodology management of freight forwarding companies. This is possible only using modern mathematical methods and information technologies that will improve the operation of freight forwarding companies. The article presents a theoretical exposition of the basic processes of interaction between participants in freight forwarding system. The article may be of interest to specialists of freight forwarding companies.

Trade-off optimal decision of the problem of software system architecture choice

Abstract: The methods of software architectures examination are discussed in the paper. It is shown that this is multicriteria hierarchical problem. For its solution, modified Analytic Hierarchy Process (AHP) is applied. Nevertheless, general result of software architectures assessment hides influence of each quality criterion on the final value and correlations between criteria too. Therefore, it is proposed to investigate this problem via examination of criteria comparability by replacement and examine sensitivity the result of alternative architectures assessment as well, and optimization of trade-offs between quality criteria.
