Equipment to vehicles energy recovery simulation
Ranuša, Matúš ; Jurík, Miroslav (referee) ; Nevrlý, Josef (advisor)
The bachelor thesis deals with design and construction of an experimental device – stand for simulation and recovery energy at utility vehicles. The first parts of the thesis describe principle and process of experiment in the University of Wisconsin Madison and thesis deals with selection of hydraulic components in cooperation with company Bosch Rexroth. The second part of the thesis deals with calculation and construction proposal of the flywheel which meets the requirements of mathematical model and other parts of model. Result of the thesis is complete 3D model of experiment stand suitable for tests energy recovery in applications. Precise determination of the effectiveness of hydrostatic recovery is one of the objectives of experiments that will be implemented at the test stand.

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.

Design of valve block for hydrostatic recuperative module of vehicle
Ranuša, Matúš ; Robenek, Dětřich (referee) ; Nevrlý, Josef (advisor)
The Master`s Thesis deals with design and construction of a valve block for a hydrostatic recuperative module of a vehicle with a direct application on pneu tyred roller AP 240H produced by the AMMANN company. The thesis aims to analyze recovery functions of the valve block in several operating modes of the roller, followed by a selection of the right hydraulic components from the perspective of predefined parameters and pressure differences. Design specifications are based on measurements and mathematical simulations on the experimental stand. The experimental stand for this application has been developed at 1:4 scale as compared to a real vehicle. The thesis includes also design of the supporting console for the module on the frame of the vehicle. The Master`s Thesis is a part of project EUREKA with cooperation Bosch Rexroth.

Hydromobil - design of mechanical-hydraulic recovery of car kinetic energy
Stodolák, Michal ; Robenek, Dětřich (referee) ; Nevrlý, Josef (advisor)
This diploma thesis deals with the structural design of a vehicle powered by pressure fluid that is stored in a hydraulic-pneumatic accumulator. The first part described the types of energy recovery, especially hydraulic recovery. Furthermore there are outlined basic parameters of the design of the vehicle driving mechanism. The second part describes the design of hydromobile with emphasis on the chassis, especially the driving and braking system. Additional information on the individual parts of the chassis, that are put through the stress analysis. The final part deals with the actual manufacturing of the hydromobile and is followed by the resume of the thesis.

Hydromobil - design of hydraulic part and transmission
Mikula, Martin ; Robenek, Dětřich (referee) ; Nevrlý, Josef (advisor)
This thesis covers the design and the construction of vehicle, which is powered by pressured fluid. The vehicle has driving system based on mechanical – hydraulic recuperation of kinetic energy during braking of vehicle. Her secondary part is used only by the start of vehicles. The thesis describes possibilities of kinetic energy recovery and in more detail explaines kinetic energy recovery with use of hydraulic systems and their practice use. The main part of the thesis contains a design of hydromobil with demonstration of individual options in outline. The selection of the whole hydraulic connection and transmission is described in detail as well as the construction of particular components of the vehicle.

The use of extended reality in the initial inspection of welded steel structures for the production of hydraulic aggregates
Losová, Jana ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This bachelor's thesis discusses the involvement of augmented reality in the process of incoming inspection of welded steel structures used for the production of hydraulic aggregates at the Bosch Rexroth company. The goal was to create and apply a proposal for a new procedure, according to which the material received from suppliers will be inspected. The Twyn program from Visometry company was chosen for the implementation of the proposal based on the head of the quality management department. The practical part showed that approximately 50% of the time can be saved by using this program in the dimensional incoming inspection process. The final part of the thesis discusses the other parameters involved in the savings and suggests further possibilities of using the purchased program.
