Engineering Mechanics 2023
Radolf, Vojtěch ; Zolotarev, Igor
The proceedings contains papers presented at the 29th International Conference on Engineering Mechanics, which has been held in OREA Resort Devět Skal in Czech Republic under auspices of the Czech Society of Mechanics and being a part of IFTOMM (The International Federation for the Promotion of Mechanism and Machine Science) activities. As it corresponds with character of the conference, this proceedings consists of several topic oriented parts: Biomechanics, Fluid mechanics, Dynamics, Fracture mechanics, Mechatronics, Reliability of structures, Mechanics of solids, Technological processes, Thermodynamics. The volume represents a well-balanced overview of theoretical, numerical and experimental work on fundamental and applied studies.
Experimental and numerical investigation of the frequency-modal properties of the switch box
Zolotarev, Igor ; Pešek, Luděk ; Bula, Vítězslav ; Šnábl, Pavel ; Gabriel, Dušan ; Mračko, Michal ; Masák, Jan
The research is linked to increase of seismic resistivity of data board switch boxes. Therefore we deal with numerical modelling of the box for finding the hot spots and designing appropriate modifications. This paper deals with numerical and experimental frequency-modal properties of the switch box and mutual comparison for numerical model validation.
Závěrečná zpráva o řešení projektu MPO čís. CZ.01.1.02/0.0/0.0ú20_321/0023673
Zolotarev, Igor ; Pešek, Luděk ; Gabriel, Dušan ; Procházka, Pavel P.
Projektu MPO s názvem Vývoj rozvaděče pro těžké podmínky a snížení rizik ohrožení kritické infrastruktury byl zaměřen na výzkum, vývoj optimalizované konstrukce a zajištění konfigurační technologie pro opakovanou produkci různých variant modulárního systémového rozváděče pro použití v těžkých podmínkách a snížení rizik seizmického ohrožení, pro zajištění spolehlivosti kritické infrastruktury. Výstupem má být prototyp seizmicky robustního zařízení s dynamicky odlehčené konstrukce, vysokou spolehlivostí funkce sestavy rozvaděče a elektrovýzbroje a SW aplikace pro interaktivní návrhy a dokumentaci.
Dynamics of Machines and Mechanical Systems with Interactions, DYMAMESI 2023
Zolotarev, Igor ; Pešek, Luděk ; Kozień, M. S.
The aim of the DYMAMESI is to facilitate the exchange of up to date information and knowledge among specialists in structural and multibody dynamics, in coupled interacting systems as aero-elasticity, hydro-elasticity, biomechanics, systems with feedbacks and mechatronics. The colloquium DYMAMESI 2021 is cofunded by the Strategy AV21 initiative of the Czech Academy of Sciences of the Czech Republic, and in 2021 will be hosted by Cracow University of Technology, Institute of Applied Mechanics, Section of Dynamics of Systems.

Modal analysis of a container with measuring equipment for space mission
Zolotarev, Igor ; Bula, Vítězslav
This paper continues investigations of some measuring equipment for space mission. The frequency-modal properties a container with several slots and measured desks are studied. The natural frequencies and corresponded modes obtained using measuring methods are presented for several combinations of the container components.

Dynamic and heat transfer analysis of a container with measuring instruments for space probes
Zolotarev, Igor ; Bula, Vítězslav ; Šnábl, Pavel ; Gabriel, Dušan ; Dobiáš, Jiří ; Masák, Jan ; Snížek, Jan ; Souček, Jan
Rocket boosters and spacecraft are subject to intense acoustic environments during launch, which induce high levels of vibration in structural elements and equipment. In addition, elastic structural interactions with propulsion systems and flight control systems can produce low-frequency, high-deflection flight instabilities. Natural vibration of the container with measuring equipment were studied by numerical and experimental methods in the laboratory of Institute termomechanics CAS. Heat transfer analysis inside the container was made by FEM with respect to the conditions during start of the rocket and work in space.\n
