Transmission of Linear Pneumatic Cylinder
Bedeč, Csaba ; Mazal, Pavel (referee) ; Nevrlý, Josef (advisor)
The main subject of this bachelor's thesis is analysis and design of a mechanism for converting linear motion to rotary swinging motion used as door drive in the buses. The first part contains analysis and application of the applicable types of mechanisms. The work contains analysis and design of a cam-type mechanism in the second part. The analysis of the designed variants and selection of optimal parameters of the proposed mechanism is the last part.

Structure and Use of the Measuring System for Research of Lubrication Device
Brhlík, Rostislav ; Omasta, Milan (referee) ; Nevrlý, Josef (advisor)
This work deals with an adaptation of the measuring system for the functional analysis of the lubricant divider. Within the new structural design, there were used manometers, flowmeters and dynamic scales to determine the properties of the lubrication system; data acquisition card and the appropriate software were designed too. The methodology of data measuring and analysis were also elaborated. The methodology is based on the experience from measuring, which was realized with the lubrication system OK - 02 from Tribotec Company. Finally, the cascade lubricant dividing system was designed. This is a newly designed flow divider with an innovative internal layout. The aim of the proposed measurement system is an optimization that will lead to effective dividing of lubricating mixture and applying the necessary amount of lubricant to wheel flange.

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.

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.

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.

Mechanical-hydraulic model of vehical energy regeneration
Pisklák, Jan ; Vrbka, Martin (referee) ; Nevrlý, Josef (advisor)
This bachelor thesis is a research about mathematic-physical model of vehicle’s kinetic energy regeneration. Mr. Pourmovahed A. et al. were dealing with this problem. He used the method of the determinated thermal time constants. Pourmovahed continued in study reports written by Green W. L. and Otis D.. His scientific work covers the analytical treatment which is compared with an experimental tests.

Models of vehicle´s kinetic energy recovery
Fic, Miloslav ; Vaverka, Michal (referee) ; Nevrlý, Josef (advisor)
The bachelor thesis deals with analysis of existing knowledge in the area of vehicle kinetic energy recuperation models. This analysis is mainly focused on hydrostatic regenerative braking system models. This paper introduces stances of some authors, mathematic relationships and program tools useful for simulation of these models. Afterwards is estimation of shown studies and at least is presented future development of hydrostatic regenerative braking systems. This paper gives a sight of hydraulic recuperation system problems and it could be used as the theoretical element for next research in recuperation models area.
