Elements of experimental equipment for research energy recovery of vehicles
Vašíček, Jakub ; Jurík, Miroslav (referee) ; Nevrlý, Josef (advisor)
Bachelor thesis is focused on selection of hydraulic components for experimental device – stand for research on hydrostatic recovery of kinetic energy of heavy vehicles for civil engineering, public transportation or utility. Main supplier of hydraulic components is – Bosch Rexroth. Thesis primary pays attention to selection and comparation of hydraulic components, it does not deal witch construction or mathematical model. Part of this thesis is concerned with future development in the field of hydrostatic recovery of energy. Main purpose of experimental stand is simulation of operational conditions of heavy vehicles, to gather information about efectivity of energy recovery and to help in making suggestions in construct solution for chosen conditions. Concrete output is analysis of suitability and construct solution for road roller AMMANN AP 240 H.

Simulation of the energy recovery circuit function
Kubíček, Ondřej ; Ficza, Ildikó (referee) ; Nevrlý, Josef (advisor)
This bachelor thesis describes the design and optimization of a mathematical model for simulating the hydrostatic energy recovery systems. The mathematical model together with the experimental stand should be used to simulate the operating conditions of vehicles using the hydrostatic energy transmission. These include vehicles for collection of municipal waste, public transport vehicles, or for heavy construction machinery. The paper summarizes the current efforts in the design of analytical models, describes the program developed in MATLAB, and is devoted to analyzing the influence of individual input parameters on the output calculation.

The AmBe Laboratory Neutron Source Field Determination Using Experimental Stend
Jelínek, Martin ; Šťastný, Ondřej (referee) ; Katovský, Karel (advisor)
This master’s thesis provides a comprehensive overview of the conventional neutron sources from the perspective of reactions which lead to the production of neutrons, advantages, disadvantages, properties and their possible utilization. In the relation to the assembly of the laboratory neutron source and the unique experimental stand “Candle” basic methods of the neutron field analysis are outlined and two of them, the neutron activation analysis and the calculation using the MCNP software code are discussed in depth to apply and compare these methods. The experimental part deals with the realization of neutron activation analysis from its design itself, through gamma spectrometry to the cadmium ratio calculation. In compliance with the measurements, a calculation with MCNP code was run and both methods were evaluated and compared. The computation is complemented with the analysis of radiation situation on the borders of the supervised area, which is compared to the legal limit.

Test bench for analysis of energy recovery in experimental vehicle
Indruch, Jiří ; Čermák, Jan (referee) ; Nevrlý, Josef (advisor)
The diploma thesis deals with design of an experimental test bench for recovery energy simulation at machines with hydrostatic energy transmission. This work describes choice of connection and selection of hydrostatic and other components. A first part of the thesis deals with calculation and design of the flywheel whose is its rotational kinetic energy corresponds in a certain scale to translational kinetic energy of the experimental vehicle. The thesis outlines the efficiency of transformation of rotational kinetic energy to pressure energy its accumulation and subsequent conversion back to rotational kinetic energy. Precise determination of the effectiveness of hydrostatic recovery is one of the objectives of experiments that will be implemented at the test bench. The task of the measurement and physical-technical analysis to be conducted at the manufactured test bench is primarily to obtain data at for the precise control of the hydrostatic energy recovery system to maximize its efficiency.
