Race Car Suspension, Springing, Damping
Šťastný, Jan ; Zháňal, Lubor (referee) ; Blaťák, Ondřej (advisor)
The main subject of this bachelor project is overview of suspension, springing and damping methods structural design in racing car. Attention is payed especially to automotive races which are under sponsorship of ACR (Autoclub of Czech Republic). Firstly is placed issue which notify main sort and princip of suspension, springing and damping function. In the next chapter is summary of technological restrictions and prescripts for racing car structural design. Next chapter refers about the most used types of structural designs for given competition. The last chapter considers development trend of suspension, springing and damping systems in racing cars.

Motocross Motorcycle Rear Suspension
Křivánek, Tomáš ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
The rear suspension of the motorcycle fundamentally influences the driver's handling, safety and comfort. It is important to address the issue of rear suspension. The bachelor thesis describes various structural arrangements of the linkage, the function of the rear shock, the spring with the coil and the air spring. It compares the characteristics of the linkage in two specific motorcycles.

Suspension Systems of Military Vehicles
Jirout, Petr ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This bachelor thesis discusses different systems of suspension, springing and damping of military vehicles. It also deals with commonly used systems of springing and damping, its advantages and disadvantages and shows practical examples of constructional solutions of such systems in vehicles used by the military. The thesis debates the use of electronical systems of suspension for military vehicles.

The production of cover blowers
Soldán, Josef ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
This thesis is focused on the production of cower blowers from steel sheet 1.4541. As the best method for producing of this part was selected bending in the bending press. This choice was based on literature review, geometry of bended part and amount of production order. For each bend was calculated bending force, position of the neutral layer and size of the springback. Bending tools and bending press were chosen depending on the biggest bending force from the bends. Developed length of the part was calculated by the position of the neutral layer. All of the above calculations were numericaly verified by the ANSYS simulation software for the last bend.

Buggy Concept Design
Richter, Vojtěch ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
The aim of this bachelor thesis is to create instruction for the construction of a terrain buggy. It’s research of used technology, but there are also key components calculation included. The thesis is divided into five parts. In the first part, there is a research of the components of the racing vehicle and there are some equations for calculation of important parameters. Furthermore, there is layout and dimension of main components and the frame. In this part is also solved storage of the engine in the frame. The third part is devoted to the calculation of the necessary driving force of the vehicle and the parameters of the braking system. The following section discusses the concept of suspension and damping with respect with favourable kinematics of the system.

Vehicle Hydropneumatic Suspension
Koudelka, Roman ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
The main task of this bachelor’s thesis is introduction of readers with main principles of hydropneumatic suspension. The introductory part, which aims to outline the historical background of the system, continuously follows the description of the principle of its function. This part also contains the typical features of this suspension system. This type of suspension is used at different types of vehicles, the specific applications are mentioned in the next chapter. The last section is about designing suspension for special military vehicle.

Computational Analysis of Electric Car Ride
Procházka, Vojtěch ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
The topic of bachelor thesis is the suspension of electric vehicles and its comparison with conventional cars. The research part describes properties of electric vehicles and their influence on the design. The increase in their total weight due to batteries and chassis solutions is being investigated especially. The next section is focused on electric motors, especially electric in-wheel motors, which represent a significant increase in unsprung mass. The next chapter describes the effect of suspension and its importance in terms of driving comfort and safety. In the computational part, the influence of the increased sprung and unsprung masses, which were defined in the search, is analyzed using the quarter car model in the MATLAB program. These results are evaluated in conclusion.
