Axle Limited-Slip Differential
Csémi, András ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
The topic of this master‘s thesis is the axle Limited-slip Differential. The first part is devoted to the description of types of differentials open, locked or self-locking. The next part describes the procedure of creating a mathematical model for the simulation of vehicle movement based on input parameters and subsequent comparison of vehicle behavior with open and locked differential. The final part of the work based on data obtained from the model with a Limited-slip Differential is devoted to the design of a differential for a vehicle with one driven axle.

Computational Model and Analysis of Vehicle Driving Dynamics
Mrázek, František ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The bachelor's thesis deals with the creation of a computational model and analysis of vehicle dynamics in connection with the principles and rules that are closely related to vehicle dynamics. We will use the key physical phenomena related to the driving dynamics of the model vehicle, suitable for modeling and analysis. The model will demonstrate the driving dynamics of vehicles in several appropriately selected situations and creates the possibility to compare the results with data obtained from freely available publications and tests.

Bicycle suspension test stations
Volánka, Lukáš ; Růžička, Bronislav (referee) ; Mazůrek, Ivan (advisor)
This work deals with the design of a bicycle suspension testing station. Currently, new suspension technologies are still being developed, especially for mountain bikes, which are intended for very rough terrain. For this development of new technologies, it is necessary to have a suitable station that enables experimental verification of driving characteristics, ideally in laboratory conditions. The key features that can be evaluated in a bike are riding comfort and grip. The designed station uses a cylindrical road simulator placed under the tested suspension (wheel). Speed bumps are placed on the cylinder of the simulator, which excite vibrations in the bike when passed over, which simulates driving on a bumpy road. At the station, it is possible to evaluate the properties of the front and rear suspension, while the bicycle is always clamped to the station by the axis of the untested suspension. During the tests, the riders weight is replaced by additional weights placed on a rack that connects the seat and head tube of the bike. The additional weights can be moved to imitate different positions of the cyclist while riding. A virtual dynamic model was created for the test station, which makes the experiments much more efficient. The simulation model was designed and tested in MSC Adams software. The test station together with the virtual model forms a simple tool that enables quick and efficient testing of the quality of bicycle suspension.
