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 ...
The influence of grooves on the behavior of steel tube shock absorbers
(Proceedings of the 7h International Congress of Serbian Society of Mechanics, Sremski Karlovci, Serbia, 2019)
Major function of railway vehicles absorbers is to absorb energy through controlled deformation during frontal rail vehicle collisions. The results presented and discussed in this paper is a part of the research of one ...
Stress concentration factors in re-evaluation of design solution
(Serbian Society of Mechanics and Faculty of Technical Sciences Novi Sad, 2015)
The failures of various parts of mechanical systems in powe industry are the lessons that should be learned thoroughly. Every behaviour of structure close to design encelope must be ecxamined carefully in order to minimize ...
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 ...
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. Unexpected
failures of gas cylinders occur despite of fact that the design, manufacture route, quality control, ...
Simulation of the kinematic hardening of AISI 316 steel by nonlinear finite element analysis
(Serbian Society of Mechanics and Faculty of Technical Sciences Novi Sad, Serbia, 2015)
The coupled non-linear transient calculation is performed and explained in order to simulate the kinematic hardening behavior of AISI 316 steel and the Finite Element Method (FEM) is used for presented simulation. The ...
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 high
stresses during regular working life and, from a safety
and operational aspect, are the most significant
components of a power generation system. Depending
on the ...
Theory of critical distances in analysis of the influence of tooth profile on gears bending capacity
(5th International Conference on Power Transmission BAPT2016, 2016)
The fatigue cracks and failures in tooth roots are still one of the most common problems in gear pairs operation.
Therefore, the application of new methods and up-to-date calculation procedures is welcome. This paper ...
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. ...
Changing the structure of concrete after exposure to frost
(Faculty Of Civil Engineering Subotica, 2014)
Concrete testing can be done at micro, mezzo and macro level. Tests at the macro level are the most common and are the ultimate engineering approach, and include testing and comparison of quantities such as commpresive ...
