Spring and Damper Tester
Šulák, Jakub ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This work deals with the springs and dampers questions. It focuses on their classification, characteristics and testing. The main part of this thesis describes the design and sizing dimensions of machine for measuring characteristics of automotive springs and conceptual design of machine for detection characteristics of hydraulic shock absorbers.

Device for Spring Dismount and for Spring Characteristics Measurement
Mazura, František ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
The presented master’s thesis is focused on the design of device for spring dismount from shock absorber and measuring of its spring characteristic. Then is the thesis focused on the design of device for measuring the spring characteristic of anti-roll and torsion bars. The introductory part of the thesis describes the basic distribution of springs and their properties and also design variants of wheel suspensions. Next part introduces devices already available on the market. The following sections aim to the design of stated devices itself, i.e. the description of their parts and functions, the definition of output parameters and stress-strain analysis. Both designs, including the analyses and technical drawings, were created in Autodesk Inventor software.

Dynamic Model of Air Suspension System
Janečková, Radka ; Zháňal, Lubor (referee) ; Fojtášek, Jan (advisor)
This master’s thesis is about creating a dynamic model of pneumatic suspension. At first reader gets to know some general information about pneumatic suspension like: classification of this type of suspension, historical development and how modern air suspension systems work. Next, there is review of some created analytical models of this type of suspension. Last but not least, the new dynamic model of air suspension is created in the software ADAMS/Car. It is tested in different types of analysis, such as quasistatic or dynamic suspension analysis and then the model is implemented in the full vehicle Tatra T158 4x4 and more analysis are made. The new model is then evaluated in terms of pros and cons.
