Engineering design of a fullsuspension mountain bike frame
Zvozil, Ondrej ; Lošák, Petr (referee) ; Březina, Lukáš (advisor)
The aim of this bachelor thesis is designing of a full-suspension mountain bike frame. At the beginning of the thesis mountain bikes are divided into categories, the function of a shock absorber is described and issues of bike kinematics and related characteristics are clarified. The thesis also describes properties of the most used materials for bike frames manufacturing. Subsequently, the most common systems of rear wheel linkage are analysed. Next, the requirements for own design are identified in terms of geometry, construction, kinematics and a creation of its 3D model in SolidWorks software. The characteristics of designed frame are analysed by specific software Linkage X3. Then a static analysis in Ansys software is made in order to select bearings for individual pivots. The final part of the thesis is dedicated to visualisation of designed frame.

Effect of Suspension Kinematics on Vehicle Handling
Trnková, Lucie ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This diploma thesis deals with effect of suspension kinematics on vehicle handling. In the first part of the thesis, there are the basic parameters of suspension kinematics introduced. In order to perform the simulations, two multi-body vehicle models are created, one of which is derived from an off-road vehicle, for which there has been a significant change in suspension. For each model, there further is a description and comparison of the kinematic characteristics of different settings variants of their suspension introduced. The main part of the thesis deals with the analysis effect of individual suspension changes on vehicle handling during the selected driving maneuvers. The results of the simulations are qualitatively and quantitatively evaluated, and the resulting findings are in the conclusion summarized.
