Measurement and visualization of parameters in hydraulic circuits
Říman, Matěj ; Kroupa, Jiří (referee) ; Houška, Pavel (advisor)
This bachelor's thesis deals with measurement and vizulation of the hydraulic circuits. First part of this work introduces a selected hyraulic task. Following chapters describe the possibilities of measuring hydraulic parameters, along with the principles of pressure sensors, flow and temperature. The following section describes measurement application in NI LabVIEW which is used to wiew and export relevant data related to measuring. The last chapter is an evaluation of the application, along with a demonstration and description of output measurement

Material Handling Platform
Bábek, Tomáš ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis is focused on constructional design of workshop handling platform which is driven by linear hydraulic motor. First the types of gripping of linear hydraulic motor are described. Next part contains drafted solutions of handling platform construction. Important part of thesis is composed of statistical computing of machinery parts and their strenght computations within the frame of designed proportions. Afterwards the bearings are chosen according to thickness of shaft and the hydraulic motor and the diagram of hydraulic circuit are designed. At last controlling computations are done and assembly and weldment drawings are created.

Horizontal splitter for firewood
Čechman, Jan ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The goal is a brief search of types of wood-splitters and own design of wood splitter, which fulfils requirements. CAD model has been made and also control calculations of suitability of chosen parts if necessary. Wood-splitter with high production of wood, big splitting force and possibility to run in home conditions has been successfully designed.

Hydraulic pullers
Pavelka, Roman ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deals with the mechanical proposal of hydraulic puller. Furthermore, it includes the detail design solutions. The project also includes the calculation of the hydraulic puller parameters: maximum pushing force is 60 kN, speed of movement is 0.1 m s-1. This work also contains of stress analysis FEM with I-DEAS software. Following part deals with the design of hydraulic circuit for driving puller. At the end of work there are options for replacements of hydraulic puller by mechanical systems.

Jib type crane
Knapec, Tomáš ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This bachelor's thesis is the design development of jib type crane with single knuckle. The target of this thesis is to develop a technical report including important strength calculations, schematic hydraulic circuit design and creating complete drawings of jib type crane that is designed for installation on mobile devices. Desired parameters of this crane are allowing horizontal rotation in 360° a vertical between 90° and maximum load capacity 1 700 kg.

Conception of a mobile splitter for wood with hydraulic drive
Změlík, Josef ; Malášek, Jiří (referee) ; Zeizinger, Lukáš (advisor)
The aim of this bachelor thesis is in the first part to evaluate basic characteristics of materials used for splitting – mainly wood. In the next part of this thesis there is focus on the availability of splitting machines on the market. Evaluation of their design and characteristics of those machines, their advantages and disadvantages. In the last part of the work I propose a new design of a splitting machine and make a model in 3D modeler Autodesk Inventor Professional 2019. For the proposed frame and all the other components of the splitting machine it was necessary to know those basic parameters like: maximal size of the wood used for splitting, maximal splitting power and required hydraulic engine extension. The documentation used for the assembling the machine was made in 2D programme Autodesk AutoCAD 2018. To this bachelor thesis there is also attached a documentation on how to assemble the wood splitting machine, documentation of welded frame, pedestal and a hydraulic scheme. In the work there are also included strengths calculations of the main parts of the splitting machine, analytically and with simulations in a programme NX I-deas 6.1.
