Testing of aircraft hydraulic systems
Suk, Filip ; Bencalík, Karol (referee) ; Třetina, Karel (advisor)
My bachelor thesis “Testing of aircraft hydraulic systems“ discusses the problems of testing particular components and complete hydraulic systems. In the first part of my work, there are specified all regulation requirements that are to be fulfilled by hydraulic systems and test conditions for testing of flight control systems. The next parts deal with the way of testing particular hydraulic elements and hydraulic liquids. The last part of my bachelor thesis is dedicated to the testing's principle of hydraulic system of landing gear including a concept for instrumentation.

Hydraulic circle of undercarriage two-way vehicle
Rozumek, Jaroslav ; Tomeček, Pavel (referee) ; Škopán, Miroslav (advisor)
The aim of this diploma thesis is a concept of hydraulic (hydrostatic) circuit of rail – road vehicle drive for the drive on communication and railway. As my work is not related to a specific type of road vehicle dedicated to a drive on railway, my work is of strictly reference nature. On request I was provided by Bosh Rexroth s.r.o. with a hydraulic scheme of two-way undercarriage (see appendix), which is also a source material for the new concept. My work is focused on interests of SaZ s.r.o., which deals with the development and rebuilding of road vehicles into rail – road vehicles. The first phase is focused on the choice of the most convenient component of railway undercarriage in accord with the assignment. The second phase is oriented on the calculation of travel parameters, dimensioning of systems with concretization of typal mark of components. A part of the second phase is also a concept of hydraulic braking system of rail undercarriage. After that follows a complete evaluation, eventually an alternative solution of given problem.

Hydrostatic drive of multi-purpose loader DAPPER
Vydra, Tomáš ; Merenda, Lukáš (referee) ; Škopán, Miroslav (advisor)
This thesis deals with design of hydrostatic drive for multipurpose loader and tool carrier DAPPER. At the beginning is research of different basic concepts and modern solutions to the problem, aided by a detailed description of competitive machine in the same performance category. Extensive comparison with other producers is included in the annexes to this thesis. Furthermore, a theoretical driving characteristic and its appropriateness is examined further on the basis of two model situations. The calculations of the individual components of the hydraulic circuit precedes drive kinematics analysis of articulated machine frame, on it final conception of hydrostatic drive is chosen. Firstly hydromotors and hydogenerator are chosen on the grounds of calculations then hydraulic hoses, filters and flow divider. Next chapters are aimed to calculations of hydraulic losses and thermal calculation of hydraulic circuit. Final part deals with introduction the final characteristics of drive. The practical parts of the work are assembly drawings with main power components and hydraulic schematic of drive.
