Diplomová práce je zaměřena na optimální modelování nýtového spoje pro tři různé konfigurace pomocí metody konečných prvků v programu MSC. Nastran/Patran. Na základě prezentovaných výsledků je možné virtuálně simulovat chování nýtových spojů při zatížení, za účelem správného návrhu před provedením statických pevnostních zkoušek. Použitím těchto MKP simulací v procesu certifikace výrobku lze významně redukovat časovou i finanční náročnost pevnostních zkoušek. Při lepším porozumění chování konstrukce lze také lépe predikovat reálnou únosnost nýtových spojů.

The diploma thesis deals with a mechanical and thermal analysis of 3-cylinder petrol engine piston with capacity of 1,2 l and maximal output 47 kW. The computation analysis was created with the use of finite element method in the Ansys application. The strain solution was created using several techniques. The 3D model was made according to a real piston in the Pro/Engineer and was partly simplified for computation. Crank mechanism forces and the load stresses were solved using Mathcad. Calculations are done for three positions of power cycle engine, where the maximal loads of the piston are ex

The aim of this thesis is an analysis of the construction of a cable trailer VARIANT 200. For the calculation of load states was used a multi body system in program MSC.ADAMS. The results from these calculations were used as lifting conditions for strength control with finite element method (FEM). All acquired results were analysed and according to them changes were made to the frame construction. Part of this thesis contains drawings documenting the above mentioned changes.

The main objective of the work was to perform a computational analysis of the hybrid (steel-composite) carrier and compare the results with the original metal carrier. Static analysis, modal analysis and frequency response were solved. Computation was performed for three different relative positions of the carrier. Static stiffness, natural frequencies and dynamic compliance have been calculated. The results were verified by an experiment performed on a scaled-down model of the carrier. Modern software products, namely MSC Patran, MD Nastran, Matlab and ProENGINEER, were used for the calculati

For the purpose of mechanical impact energy absorption in the transport industry are mainly used special profile absorbers. For highly specialized applications is required to use components that are designed for specific kind of deformation. Example of these parts are industrial-made metal foams or micro-lattice structures produced by SLM technology. This paper focuses on low-velocity dynamic loading prediction of BCC micro-lattice structure made of aluminum alloy AlSi10Mg by SLM technology (SLM 280HL). For this purpose dynamic FEM simulaton of the micro-lattice structure was developed, supple
