Physical Simulation of a Vehicle
Urbanovský, Jiří ; Pečiva, Jan (referee) ; Navrátil, Jan (advisor)
The work deals with issues from physical simulations and computer graphics. The goal of this thesis is to describe the key stones of simulation of a vehicle in real-time. It outlines physical laws describing movement and rotation of rigid bodies and springs. Physics is handled by the Open Dynamics Engine library, graphics is handled by the OpenGL library. The focus was on providing correct functionality of suspension, real behaviour of the underlay and the fluency of the simulation.

Physical Simulation of a Cloth
Řehánek, Martin ; Juránek, Roman (referee) ; Navrátil, Jan (advisor)
This bachelor's thesis concerns with simulation of material in real time. By material we mean the textile. Firstly, it will explains principle of simulation in textile, where the system of springs is used. Secondly, it will explains mathematical and physical basics needed for simulation and then describes implementation of simulation itself. In a final part the achieved results are evaluated.

Vehicle Multibody Model - Ride Comfort Evaluation
Friedl, Michal ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
This master’s thesis is concerned of ride comfort. It uses MBS simulation software MSC Adams, especially its Car module. It contains simulations of ride over the road with obstacles that represent the everyday conditions in real traffic. The main area of focus is to find acceleration data that are present on the driver’s seat and co-driver’s seat in relation on specific suspension settings which affect the ride comfort.

Using brushless d.c. motor to drive servo-unit with safety function
Rudolf, Ladislav ; Mišurec, Jiří (referee) ; Prajzner, Václav (advisor)
In this work, a proposal for BLDC motor control, which will be used as a drive linear actuator. Control with microcontroller focuses mainly aspects such as motor mode, regenerative mode, measuring rotor position sensors and measuring the motor current, which corresponds to the moment. The result of the work is focused on upgrading the existing Honeywell actuator, where the processor-controlled BLDC motor to replace the existing system and take over the actuator working function and emergency function.

Vehicles pneumatic suspension systems
Černuško, Lukáš ; Blaťák, Ondřej (referee) ; Suchý, Jan (advisor)
Bachelor’s thesis contains division of dampers for motor vehicles and describes some main types. There is structure explanation of pneumatic suspension, individual parts description and their working in other section. Further there are derived equations for calculation of fundamental properties with simplified assumptions. Equations figure out spring and damping characteristics. Main goal is to determine properties which increase the driving comfort.

Adjustable dampers of road vehicles
Šplíchal, Bohuslav ; Hejtmánek, Petr (referee) ; Vančura, Jan (advisor)
This bachelor thesis deals with the distribution and description of the activities of conventional and adjustable shock absorbers of road vehicles. It describes the dynamic of the vehicle in the vertical oscillation and the effect of damping and springs to vehicle behavior. It also describes and classifies individual suspension systems that use adjustable shock absorbers.

Principles and types of hydrodynamic valves
Havelka, Milan ; Himr, Daniel (referee) ; Pochylý, František (advisor)
This thesis deals with characteristics of the most commonly used valves in hydraulic systems. The aim was to create an overview of available features and define their brief characteristics. The emphasis was placed on their function and principles of task performance in a hydraulic circuit. The second part of the thesis is aimed at solving the issue of valves oscillation and subsequent optimization of constants that function as factor dampping.
