Design rámu horského kola / Design of mountain bike frameHaman, Martin January 2010 (has links)
The aim of master thesis is the design of full suspension mountain bike frame for racing and competition use. The base of the design solution is selection optimal conception of suspension which influence external design of the frame. General benefit of this concept is utilizing specific properties of carbon composite for design of funkcional frame parts and their technical and visual integration. Important part of this work is design of frame details: rear ends, rear shox's link and duct of the bowdens, wires and brake hydraulic housing.

Hodnocení účinnosti brzdového systému osobního automobiluPutna, Michal January 2017 (has links)
This work focuses on car braking systems. The theoretical part describes types of brakes used in vehicles, construction parameters of drum and disc brakes. This work also describes the electronic system ABS and possibilities of its braking effects on cylinder and platform braking test rooms. Practical part of this diploma thesis focuses on measuring of the braking forces of Škoda Superb in time. The measurement was performed with both active and inactive systém ABS. The results where compared with the braking results of a Volkswagen Golf Variant. Amount of force and decceleration in time measured were used for results evaluation. Results show that the systém ABS has a significant effect on braking. The length of braking is increased, but the car keeps its maneuverability.

Métallogenèse de l'uranium dans la région de Litsa (Péninsule de Kola, Russie) / Uranium metallogenenis in the Litsa district (Kola Peninsula, Russia)Serov, Léonid 24 June 2011 (has links)
Le district de Litsa est une région de la Péninsule de Kola particulièrement prometteuse pour la métallogénie de l'uranium. Présentant toutes les caractéristiques d'une province métallifère, ce district a enregistré une histoire géologique complexe avec des enrichissements successifs en uranium. Trente anomalies uranifères y sont observées, estimées à 102 000 tonnes (IAEA nomenclature), pour une teneur moyenne de 0,01%. Elles sont encaissées dans différentes formations de niveau structural et d'âge différents, depuis l'Archéen jusqu'au Calédonien. La minéralisation présentant les teneurs en uranium les plus économiques sont des veines de pechblende observées autour du complexe granitique de Litsa-Araguba, où sont présents des protolites, des structures et des phénomènes épigénétiques favorables / The Litsa district is one of the most interesting areas of the Kola Peninsula with respect to uranium metallogenesis. Presenting all the features of uraniferous province, it endured a protracted geological history with several successive uranium enrichments. There are over 30 uranium occurrences and manifestations, totally estimated at 102,000 tons in Speculative Resources (IAEA nomenclature), with an average grade of Uranium 0.01%. They occur at different stratigraphic levels of the geological succession in the district: Archean, Paleoproterozoic, Mesoproterozoic and Paleozoic. Uranium content in the geological formations gradually increases during the geological evolution of the Litsa district from Archean to Paleozoic. The most abundant and probably prospective for the economic-grade uranium mineralization is Paleozoic pitchblende vein type, located around the Litsa-Araguba granitoid complex, where favorable protoliths, structures and epigenetic processes are encountered

Zadní těhlice vozidla Formule Student / Formula Student Rear Wheel CarrierNovák, Pavel January 2011 (has links)
The aim of this thesis is to create a design rear upright for a racing Formula Student category car. It is necessary to propose a design group of the rear wheel assembly with the upright with all requirements related thereto, for example solutions camber settings. Everything is modeled using the CAD system. There is developed computational model which is placed in ballast states of strain and stress analysis by finite element method. There is also designed a suitable material for the production of the rear upright which is optimized. The conclusion deals with the inclusion of the proposed arrangement in the overall vehicle assembly and is concluded with evaluation and suitability of the proposed solution.

Návrh zařízení pro měření elastokinematiky zavěšení kol / Design of Device for Vehicle Suspension Elastokinematics MeasurementPohořelský, Petr January 2017 (has links)
In my dissertation, I was concentrated mostly on a pliability of problematic of wheel´s suspension. My thesis is mostly a detail design proposal of a device, which is determined for a measurement and record of wheels suspension system´s elastic deformation. My theoretical part of this thesis is a search of existing devices and its problematic. The other part of my dissertation is a description of individual parts of my designed device and also an analysis of designed components´ intension. My thesis includes calculation, for case of realisation. There is also a design of measuring chain, methods of results´ evaluation after measuring with this device and theoretical analysis of measurement´s inaccuracy.

Vliv rotace kol na aerodynamické charakteristiky vozu / Influence of rotating wheels on vehicle aerodynamic characteristicsOslizlo, Aleš January 2010 (has links)
The diploma thesis is focused on computational examination of influence of boundary condition settings in CFD software on the final aerodynamic characteristics of a vehicle. The flow analysis is carried out around a vehicle with and without the rotation of the wheels and along with the stationary and moving road. Furthermore, there is demonstrated the method of the CFD model composition and there is described the influence of rotating wheels on vehicle aerodynamic characteristics.
