Influence of the air pressure and oil amount to the temperature of the high-speed bearings lubricated by oil mist
(Emerald Group Publishing Ltd, Bingley, 2022)
Purpose The purpose of this paper is to improve the lubrication and remove as much as possible of the heat generated in the bearing assembly, embedded in the jet engine. Design/methodology/approach To determine the necessary ...
Thermal parameters defined with graph theory approach in synthetized diamonds
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The Nanocrystaline diamonds are very important biomedical material with variety of applications. The experimental procedures and results have been done in the Institute of Functional Nanosystems at the University Ulm, ...
Influence of the running-in process on the working ability of contact surfaces in lubricated sliding conditions
(Sage Publications Ltd, London, 2022)
The influence of the running-in process operating parameters on tribological properties of the block-on-disc samples in lubricated sliding conditions is analyzed and discussed in detail. Different running-in regimes are ...
Experimental and numerical stress and strain analysis of the boiler reversing chamber tube plate
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Boilers are one of the most used units for both heat generation plants and industry systems. Their operation is subjected to different working loads and maintenance requirements. Exploitation experience points out critical ...
Thermo-mechanical analysis of linear welding stage in friction stir welding influence of welding parameters
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The influence of friction stir welding parameters on thermo-mechanical behav-ior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are ...
Identification and control of a heat flow system based on the Takagi-Sugeno fuzzy model using the grey wolf optimizer
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Even though, it is mostly used by process control engineers, the temperature control remains an important task for researchers. This paper addressed two separate issues concerning model optimization and control. Firstly, ...
Control of a DC motor using feedback linearization and gray wolf optimization algorithm
(Sage Publications Ltd, London, 2022)
The aim of this study is to investigate nonlinear DC motor behavior and to control velocity as output variable. The linear model is designed, but as it is experimentally verified that it does not describe the system well ...
Performance characteristics of lubricant based on rapeseed oil containing different amounts of metal-containing additive
(Emerald Group Publishing Ltd, Bingley, 2022)
Purpose The purpose of this study was to investigate the biobased (rapeseed) oil with the addition of different amounts of metal-containing additive in a steel-bronze tribological system. The additional purpose was to find ...
Optimal airfoil design and wing analysis for solar-powered high altitude platform station
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The ability of flying continuously over prolonged periods of time has become target of numerous research studies performed in recent years in both the fields of civil aviation and unmanned drones. High altitude platform ...
Error bounds for gaussian quadrature formulae with legendre weight function for analytic integrands
(Kent State University, Kent, 2022)
In this paper we are concerned with a method for the numerical evaluation of the error terms in Gaussian quadrature formulae with the Legendre weight function. Inspired by the work of H. Wang and L. Zhang [J. Sci. Comput., ...
