Vehicle suspension design and testing methods
Šenkeříková, Veronika ; Tobiáš, Martin (referee) ; Fojtášek, Jan (advisor)
This bachelor's thesis is dedicated to suspension systems and their typology. Furthermore, the basic geometric parameters of these systems are discussed in the thesis. Types of suspensions (axles) are classified according to the interdependence of individual wheels. Subsequently, the thesis provides an overview of simulation software for chassis development and testing in the virtual phase of development. These are divided according to computational principles, result evaluation, and environment. The last section addresses issues related to chassis testing and its properties as a whole, testing individual chassis components to verify durability etc. The thesis includes specific representatives of testing conditions. For each chassis component, a representative from each chassis subsystem is selected. This thesis provides a current overview of methods and tools used in the automotive industry for development and testing. It demonstrates the importance of both virtual testing and testing on testbeds for already finished products.

Anylytical solver for strength calculation of railway axles
Fišer, Petr ; Náhlík, Luboš (referee) ; Vaverka, Michal (advisor)
This master thesis deals with wheel set axles of rail vehicles, their design and methods of implementation stress analysis. In this work, I created a powered locomotive wheel set: axle and wheel. For the purpose of the design department of the Bonatrans Group a.s. company I developed an analytical solver, which allows creating stress analysis, which will be used for verifying finished design and in addition it allows printing of stress analysis as report for the railway´s offices. Next step was a stress analysis of this design of axle in this analytical solver.

Frame trailer with tipping body
Uher, Milan ; Ješina, Miroslav (referee) ; Škopán, Miroslav (advisor)
This diploma thesis deals with the design of the frame of a trailer with a tipping body. Its main contents are stability inspection of a carrying frame, further then designing suitable construction adjustments including their check calculations of case of stress. The stability inspection of the frame is carried out by means of the finite element method. A draft of the drawing documentation of the frame is as well included in this thesis. This diploma thesis was created in collaboration with the SVAN Chrudim company, Ltd.

Design of the Group E2 Vehicle for the Hill Climb
Malchárek, Martin ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis describes the design of the E2 hill climb car and it is design by following the FIA rules. Next parts are focused on detailed design of the front and rear suspension and design of the frame. Diploma thesis is processed using CAD system Autodesk Inventor 2011, in which was created all sketches and models. The suspension geometry during bound and rebound movement of the wheel was made in MBS system MSC Adams 2010. FEM analysis of the frame was made in ANSYS Workbench 12.1.

Kinematics analysis of race car suspension
Jurka, Adam ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This bachelor thesis is aimed on kinematic analysis of the race car suspension. In the first part of the thesis geometry parameters of suspension and their influence on driving behavior are explained. Additionally measuring methods of suspension geometry and their use in real life applications are described. Then kinematic points of the race car Peugeot 208 R2 are found and measured using 3D optical method. For better evaluation of measured data virtual model of each axle is created in Adams Car simulation software. After that kinematic analysis is performed. This analysis describes change of parameters in car suspension depending on wheel trajectory. As a conclusion results of the analysis are discussed. Moreover new methodology for better and more precise evaluation of car suspension analysis is introduced and described.
