Modal analysis of the hydro turbine shaft with cracks
(Abstracts of 14th International conference Dynamical Systems - Theory and Applications, 2017)
The design process for the elements which are the parts of the structures and equipment in power industry includes both of stress and strain state calculations, as well as an analysis of natural mode shapes and frequencies. ...
Calcium Carbonate Fillers Prepared by Means of Micronized Milling with Application in Coatings
(The Serbian Ceramic Society Conference Advanced Ceramics and Applications III: New Frontiers in Multifunctional Material Science and Processing, Belgrade, 29th September - 1st. October, 2014, 2014)
Rapid technological development in past few decades led to formation of a certain group of ceramic materials which are often referred to as “coating agents”. This term is rather descriptive because materials that belong ...
Finite element model for stress state analysis of deep groove ball bearings with defects
(Proceedings of the 5th International Scientific Conference, ”Conference on Mechanical Engineering Technologies and Applications” COMETa2020, East Sarajevo, 2020)
In the framework of Industry 4.0, new specific or improved methods formonitoring and prediction of operational conditions of machine elements are required.Ball bearings are among the elements with high impact on safety and ...
Comprehensive approach to weld repair on elements of power transmission – case study for hydro turbine shaft
(Proceedings of the The 4th IIW South – East European Welding Congress, October, 10-13, 2018, Belgrade, 2018)
Turbine and generator rotors and shafts undergo highstresses during regular working life and, from a safetyand operational aspect, are the most significantcomponents of a power generation system. Dependingon the appropriate ...
SYNTHESIS OF NEW REFRACTORY COATINGS BASED ON BASALT FOR FOUNDRY APPLICATIONS
(Science and higher reducation in function of sustainable development SED 2021., Proceednings, 2021)
This paper presents the results of research on coatings based on basalt for use in Lost foam casting process. These
coatings have not been used in practice so far. The coating compositions and the synthesis process were ...
Statistical analysis of shear strength of welds in welded fabric for civil engineering with application of new tool design
(The Association of Metallurgical Engineers of Serbia, Belgrade, Serbia, 2019)
Many new requirements in the field of testing of metals, emphasize traceabilityand accuracy of test results as of the end goal. These requirements have hiddencontext with emphasis on energy efficiency too., which is initiated ...
Gas cylinder rupture induced by local corrosion damage
(Society for Structural Integrity and Life – Prof. Dr Stojan Sedmak (DIVK), 2018)
Commercial gas cylinders are common type of pressure vessels in many health care and technical facilities. Unexpectedfailures of gas cylinders occur despite of fact that the design, manufacture route, quality control, ...
Design of the transition zone of turbine shaft to flange by biomimetics principles
(University of East Sarajevo, Faculty of Mechanical Engineering East Sarajevo, 2018)
The consideration of the optimal design of the transition zone of turbine shaft to flange has a high impact within the turbines design. The main principles of biomimetics give a new and prosperous point of view on the ...
Morphology of corrosion fatigue and stress corrosion cracks on low alloy steels
(Society for Structural Integrity and Life – Prof. Dr Stojan Sedmak (DIVK), 2018)
The fracture surface appearances are slowly changed through decade’s side by advantages in technology of steel production.Basic requirements for cleaner steels and lower energy consumption during production induce that ...
A theoretical model for vibro-impact dynamics of spur gears with tooth flanks wear
(NODYS Publications, Rome, Italy, 2019)
The main performances of involute gears operations lead to the appearance of nonlinear dynamic behaviour and impact. In this paper the influence of mild wear of the tooth flanks of gears without surface hardening on the ...
