Thermomechanical Analysis of Braking Disc
Bačovský, Marek ; Zubík, Martin (referee) ; Novotný, Pavel (advisor)
The aim of this thesis is the analysis of three types commonly used automotive brake discs in terms of their thermal and mechanical resistance on a defined braking maneuver. Another objective is to make an evaluate of the different structural solutions and compare them by each other.
Optimization analysis of brake wheel
Hrabovský, Jozef ; Vlach, Radek (referee) ; Houfek, Lubomír (advisor)
Subject of this diploma thesis is break wheel optimalization analysis. Break wheels are used in mountain bike downhill races in extreme conditions. It is the first product of this type of an emergent company that was made by the use of intuitive approach. The reason for optimalization is improper behavior of existing solution that occurred during testing. This optimalization consists of finding and analyzing existing characteristics, deciding which factors influence this improper behavior, suggesting new solution and verification of this solution. Break wheel characteristics were detected in an experiment. For realization and evaluation of this experiment, a method named Design of experiments, was selected. This method is used for elaboration of results coming from the Regression analysis. It is possible to effectively achieve the result data by using this procedure. The experiment was oriented to gain data of temperature behavior of break wheel during real load. Mathematical model was adapted on the basis of this data and finally, the calculation was made by the use of Final element method by ANSYS WORKBENCH. Calculations were also coordinated through Design of calculation, and were oriented on temperature deformation and stress. Solution achieved by the Final element method, was evaluated by the Regression analysis and served as a proposition for a new break wheel construction.
Axles of modern trucks
Vávra, Radek ; Vopařil, Jan (referee) ; Kučera, Pavel (advisor)
The main objective of this work is to present trends of modern axle trucks. There are presented the latest famous brands axle trucks. For each type has its axle design, driving properties and applicability. Furthermore, this paper describes the basic principles and structure axle’s differentials, brakes, gearboxes and wheels in the wheels.
Tractors brake systems
Pazour, Martin ; Prokop, Aleš (referee) ; Ambróz, Richard (advisor)
This Batchelor’s thesis deals with an overview of the contemporary brake system of tractors. Principles and constructions of brake systems will be described in this thetis. Then the braking dynamics will be analyzed and convenient brake system for tractor up to 90kW will be projected.
New trends and material usage in bicycle frame design
Jelínek, Vladimír ; Němec, Karel (referee) ; Juliš, Martin (advisor)
Thesis in its first part summarizes the evolution of the bicycle from the draisine to the low wheels with a focus on the material of the frame of the bicycle. Also discussed in this section is an overview of small structural modifications, which were gradually used on a bike, like Bowden brake or the first type of transmission system. In the second part, the thesis describes the operating principles and types of suspension forks and disc brakes. Mentioned are materials that are currently used for bike frames with a focus on the advantages and disadvantages of each material used and its future anticipated use.
Brzdové soustavy traktorů
Dřevojan, Martin
In my bachelor thesis I deal with the problem of tractor braking systems, its types, construction, advantages and use. I gradually describe the different braking systems and the principle of their activities.I tried to summarize knowledge about about brake systems in a comprehensive overview.
