Workshop lifting and handling devices
Benda, Petr ; Zeizinger, Lukáš (referee) ; Škopán, Miroslav (advisor)
This bachelor’s thesis deals with workshop lifting and handling devices. At the beginning these devices are divided into several groups depending on its characters and benefits. Afterwards the thesis deals with a conceptual design of a movable hydraulic crane. The attention is focused on functional calculation and strength assessment of the main parts. At the end the thesis contains a drawing documentation.

Pressure losses and heat output of the hydraulic blocks of a linear integrated hydraulic unit
Soukup, Lubomír ; Červinka, Martin (referee) ; Klas, Roman (advisor)
A common problem in the design of hydraulic systems is the pressure losses caused by movement of viscous liquid in individual elements of hydraulic circuits. These losses have negative effects on the overall efficiency of hydraulic systems and thus their overall operation. There is a change in temperature of working fluid and components (elements) of circuit due to the result of the mentioned losses. This master thesis is focused on the heat generation (output) in hydraulic cubes of a linear integrated hydraulic cubes (here in after LIHJ) which is the prototype of hydraulic lifting equipment. Losses, arising during the operation LIHJ in pipes and in hoses, can be determined numerically and experimentally. Most of hydrostatic transmitters and others hydraulic components are almost always supplied with the necessary documentation which contains all the necessary information such as experimental characteristics, etc. However problematic parts are the hydraulic blocks which are specific to their size and function. Of course, each manufacturer must prepare technical documentation including characteristics which are important for trouble-free operation of the hydraulic system. The main aim of this work is to determine pressure losses and the heat generation (output) in the hydraulics blocks by program which is used for creating geometry and computing using software like Ansys Fluent, which is based on the finite element method. If these calculations could be compared with experimental measurement technically, then heat generation (output) in both the cubes will be evaluated towards other hydraulic components and the whole system (device). The simulation results will be implemented in software which is used for calculation of heat generation in LIHJ at different operating modes and loads. Furthermore, these results will be the basis for the design of geometry of hydraulic blocks with low pressure losses which will reduce energy consumption of the device. At the end of this thesis, some advanced methods for the manufacturing of hydraulic blocks are briefly introduced, namely the method 3-D casting.
