Biomimetics design for tribological applications
(Fakultet inženjerskih nauka, Kragujevac, 2018)
Biomimetics, biomimicry and bionics are synonyms for the scientific discipline of creating new structures inspired by nature. Biomimetics systematically analyses the evolutionary processes of living organisms, their ...
Tribological properties of WC-Co/NiCrBSi and Mo/NiCrBSi plasma spray coatings under boundary lubrication conditions
(Fakultet inženjerskih nauka, Kragujevac, 2017)
The tungsten carbide based WC-Co/NiCrBSi (50/50) and molybdenum based Mo/NiCrBSi (75/25) coatings were investigated under boundary lubricated sliding conditions, and their tribological properties were analysed and compared. ...

O prenosu obrtnog momenta Kardan-Hukovim zglobom / On the torque transmission by a Cardan-Hooke joint
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Proučavana je kinemtika i dinamika Kardan-Hukovog zgloba. Kinematička analiza se bazira na teoriji složenog kretanja krutog tela. Dinamička analiza Kardan-Hukovog zgloba je izvršena na bazi Lagranževih jednačina druge ...
Integrity assessment of turbine flat cover pipe
(Institut za ispitivanje materijala, Beograd, 2018)
The turbine flat cover pipe (dimension phi 219.1x12.7 mm, and material STPG-38) is tested and cracks are found. Determination of the required wall thickness for a pipe exposed to internal pressure is done according to EN ...
Non-homogeneity effect in the spherical shell by using seth's theory
(Institut za ispitivanje materijala, Beograd, 2017)
This paper presents nonlinear deformation behaviour of non-homogeneous spherical shell examined under pressure by using Seth's transition theory. It has been seen that for increased material compressibility in thickness ...
Upravljanje popustljivosti kinematski redundantne robotske ruke promenom konfiguracije - deo I - teorijska postavka / Configuration-based compliance control of kinematically redundant robot arm Part I: Theoretical framework
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Kada je popustljivost vrha robota dominantno određena popustljivošću njegovih zglobova, generalizovana matrica krutosti robota može se preslikati iz prostora radnog zadatka u prostor unutrašnjih koordinata robota primenom ...
