Dynamics of complex systems consist of deformable bodies in contact - the new approach
(Proceedings of the 6th International Congress of Serbian Society of Mechanics, Tara, Serbia, 2017, 2017)
This paper presents the new approach for solving the non-linear dynamics of complex mechanical systems, which contains two or more deformable bodies in contact. The developing of presented approach is motivated by problems ...
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 ...
On biomimetics in machine elements design
(Manipal University Jaipur, India, 2019)
The aim of the paper is to point up the possibilities of biomimetics principles in the machine elements design. During last decades, the new requirements in machine elements design are placed in front of the experts. 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 ...
Neural network model for the condition assessment of hydro turbines
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, Serbia, 2022)
During regular operation, hydro turbine elements have complex operating conditions. In order to prevent major failures, among other common preventive measures, it is necessary to make a useful model of hydro turbine. ...
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 ...
Analysis of Hertz contact stresses for metallic material with carbides
(8th International Congress of Serbian Society of Mechanics, Kragujevac, Serbia, 2021)
Hertz contact and the resulting stress-strain state arising from the contact between two elastic solids have practical application in hardness testing, wear and impact damage of engineering ceramics, the design of dental ...
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. ...
