Rubber torsional vibration damper for a four-cylinder diesel engine
Galásek, Martin ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
The diploma thesis ‚Rubber Torsional Vibration Damper Of a Four-Cylinder Diesel Engine‘ covers all the development phases related to a design of a rubber damper for a specified engine. The individual phases of it are discussed in details throughout the thesis. At first, the construction plan of a crankshaft is given. The computational checks for torsional vibrations and forced torsional vibration are performed then. With regards to it there might be derived the basic parameters and dimensions of a rubber torsional vibration damper. The knowledge of them enables to prepare the constructional plan of a rubber torsional vibration damper. By using this damper construction plan the torsional displacements (deviations) and forced vibrations are calculated. Finally, a mechanical and thermal stress test of this damper is performed and a crankshaft production drawing is produced.

Bittner, Ivo ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This thesis deals with comprehensive study and design of recovery system of a road vehicle powered by human power. It contains an overview of different types of heat recovery devices, their characteristics, advantages, disadvantages and applicability in the construction of such a vehicle.
Differentiation within the Carlina vulgaris complex in central Europe
Mašková, Hana ; Kaplan, Zdeněk (advisor) ; Chrtek, Jindřich (referee)
The Carlina vulgaris complex includes in central Europe several forms with specific morphology, ecology and distribution. Their mutual relationships and ancestry are unclear. This fact leads to many different views on their taxonomy. The critically endangered endemic taxon C. biebersteinii subsp. sudetica was described from the Czech Republic. Its differentiation from other central-European populations has not been studied yet. For this reason, my following master thesis will focus on taxonomic re-evaluation of this complex by means of investigation of genetic and morphological variation. Powered by TCPDF (
Interspecific hybridization between Pulsatilla pratensis and P. patens
Krejčová, Nikol ; Suda, Jan (advisor) ; Kaplan, Zdeněk (referee)
This thesis deals with interspecific hybridization in sympatric populations of Pulsatilla patens and P. pratensis. The key aim was to assess karyological and phenotypic variation in the study group. DNA flow cytometry revealed three non-overlapping groups of genome sizes, corresponding to P. patens, P. × hackelii and P. pratensis. The frequency of interspecific hybridization was low, accounting to approx. 3% of analyzed plants. Morphometric analyses identified a set a reliable species-specific characters, including number of divisions the leaf, length of petiole the part of leaf, number of smaller parts of leaf and colour of blossom. Although the majority of hybrid individuals flowered and set fruits, their fertility was reduced considerably. The threat from interspecific hybridization to parental species is therefore rather low.
Personal car differentals
Csémi, András ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor’s thesis deals with the topic of car differentials with special attention to self-locking differentials. The first part is dedicated to the description of the powertrain. Then the main part is about the differentials, their division, the description of the constructions and the principle of function, with a focus on self-locking types. The aim of the thesis was to create a summary of self-locking differentials.
Řehánek, Matěj ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)

Vehicle is designed to city and relates to physically handicapped persons and elderly people. This thesis content comparison of different types of bicycles.
Human Powered Vehicle Differential
Andrlík, Ladislav ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The aim of this diploma thesis is the design of the differential of a road vehicle driven by a human force, intended for daily driving in the city with a focus on older users. The vehicle for which the differential is designed is strictly a pedal tricycle. The introduction of this thesis briefly outlines the history of pedal tricycles. The second chapter explains some technical terms relating to tricycles and bicycles in general. Further chapters of the research part describe the current structures of tricycles, the principle of a differential function in motor vehicles and design possibilities of the differential for pedal tricycles. The practical part of my work includes the design of a differential for pedal tricycle, the strength analysis of selected parts of the differential, drawings of the differential assembly, production drawings of selected parts and proposal of the torque transfer from pedals to the differential.
Car Front Axle Driveline Gearbox
Černuško, Lukáš ; Černý, Jiří (referee) ; Kaplan, Zdeněk (advisor)
Goal of the Master Thesis was to design conception of electric vehicle driveline, which is able of torque vectoring between each wheel independently and to design front axle gearbox. The aim was to use up the car on race track and to test dynamic properties of electric vehicle for follow-up development. Due to determined requirements and possible solutions the conception of driveline was designed and basic parameters were defined. The main part of the thesis contains a design of gearbox including strength calculation of gearing, the control of shafts to fatigue and elasticity limiting states, life of selected bearings. Gearbox case was subjected to FEM analysis. The last chapter uses simulation to gain vehicle acceleration. Designed electric driveline is applicable to other sport vehicles after some modifications.
