Simulation of a temperature field of the FDM printhead
Rousek, Jakub ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
The aim of this thesis is to analyze the thermal behaviour of the printhead used on RepRap 3D printers. The main focus was on heatbreak zone, where are located important processes in terms of softening and melting of materiál. For choosed printheads is looked at effect of their design on the temperature profile and lenght of thermoplastic transition phase. For the purpose of simulations, 3D models were created using CAD system. These models were then used as vase for the simulation models of temperature distribution and spreading. The prinhead used for CR10 printer reach significantly worse result of heat distribution in heatbreak for model with bolt attachment between heat block and heatsink. This attachment is increasing temperature at the bottom of of heatsink and also increasing length of transition zone. The same attachment is look at for the second type of printhead – A10M. Here is difference less noticable. The heat transfer by attachment bolts is compenzated by reducing thickness of wall in the heatbreaks. For the printhead type diamond was deemed necessery usage of insulation materiál between heat block and rst of the components. Insufficient insulation is increasing risk of clogging and thermal damage to construction supporting fan.

Analysis of selected handling devices
Rousek, Jakub ; Kašpárek, Jaroslav (referee) ; Hloska, Jiří (advisor)
The content of this bachelor thesis is a search analysis of selected intra-company manipulation devices used in electronic industry. The analysis includes description of each type, their construction and technical parameters. Practical part of thesis is focused on simulationmodelofproductionlinessupplychainwithselectedmanipulationdevice.The simulation model is created by Plant Simulation software from Siemens PLM Software. With help of this simulation model were performed series of experiments. Each variant of simulation model was analyzed and conclusions were deduced.

Analýza lanovkového soustřeďování dříví na školním polesí Lesnické akademie v Trutnově
Rousek, Jakub
This bachelor's work is dealing with analysis of the cableway transport of timberat school forest district of Czech High School of Forestry Management in Trutnov. A group of students -- teaching branch 41-56-H/01 Forestry mechanization was observed during the work, which during the technical training engages in manipulation with yarder Larix 3T. The work scrutinized a proportional discharge of performance standards students' work group by assembling and dismantling of cableway Larix 3T.
