Topology Optimization of the Hinge on Elastic Foundation
Beruashvili, Vasili ; Symonov, Volodymyr (oponent) ; Löffelmann, František (vedoucí práce)
Deal of this Master’s thesis is to modify original part shape using topology optimization by M.S.C NASTRAN, M.S.C. PATRAN and FUSION 360 software results that will define best fitted and satisfying the operating conditions for defined load and constraint conditions. The part is mounted on an orthotropic plate (sandwich panel). The aim of this thesis is to see the effect of elastic foundation on optimization result. The part will be optimized using different design objectives and constraints. Elastic foundation theoretically will change stiffness and deformation, and this will give the ability to change stresses on the part. Original and modified shape part load capacity will be compared by M.S.C NASTRAN/PATRAN software. After shape optimization, the 3D model has to be prepared for the manufacturing process which will be the most cost-efficient.

Small satellite dispenser structural optimization
Zíka, Jakub ; Symonov, Volodymyr (oponent) ; Popela, Robert (vedoucí práce)
This thesis is focused on stiffness optimization of small satellite carrying structure - the Dispenser. The first chapter is an introduction to the European space activities and also includes a brief technical overview of the European launchers. The second chapter aims to provide the finite element model description, which is used for the optimization, described in more detail in the third chapter. The fourth chapter concludes the thesis with the basic strength verification of the optimized structure.

Joining of CFRP and metal parts
Dolinský, Jiří ; Urík, Tomáš (oponent) ; Symonov, Volodymyr (vedoucí práce)
This thesis describes basic principles of joining advanced composites together and also joining advanced composites to metal counterparts. The main goal of this thesis is to come up with suitable solution of the joint between metal hinge and CFRP wing spar for flying car AeroMobil 3,0. For calculation of stress-strain analysis a special analytical method is used, which was performed by means of computer software MATLAB and Excel. Final design of the joint is performed by aid of computer software Autodesk Inventor. Submitted solution is not practically tested, hence it has to be considered as a first approximation of future design.

Hybridní lepené spoje kovových a kompozitních materiálů
Jetela, Václav ; Symonov, Volodymyr (oponent) ; Klement, Josef (vedoucí práce)
První část práce s názvem „Hybridní lepené spoje kovových a kompozitních materiálů“ obsahuje popis povrchových úprav adherendů. Rovněž je uveden aktuální ucelený přehled lepidel používaných pro spojování kompozitních a kovových adherendů. Druhá část práce je zaměřena na zkoušky smykové pevnosti hybridních spojů. Byl zkoumán vliv tloušťky adherendu, délky přeplátování a vliv přípravy povrchu na smykovou pevnost spoje. Naměřené závislosti jsou ověřeny FE analýzami s dostatečnou přesností. Poznatky a závěry uvedené v práci je možné využít pro optimální návrh hybridního spoje duralu a kompozitu.
