Innovation of suspension mechanism for mountain bike
Hrubý, Patrik ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
Bachelor´s thesis includes the description, the analyze of the issue and innovations of the bike suspension for mountain bike, including design of the geometry, shape and propose of the production in the individual production devices. Belonging work is also construction 3D model of the particular parts the bike suspension and making mechanical drawing. The next thesis hints as exploitation of the modern technologies as is reverse engineering, making models in program Autodesk Inventor or work on 5-axis CNC milling machine and their interaction.

The construction of MR damper for MTB fork suspension
Salva, Matúš ; Macháček, Ondřej (referee) ; Strecker, Zbyněk (advisor)
In MTB is front suspension very important part of bike. It ensures comfort of ride and security. This Bachelor thesis deals with the theoretical design of semi-active suspension for MTB fork. For this purpose of simulation models of suspension used adaptive damper and MR damper with Skyhook algorithm were made. Range of forces for MR damper for use in MTB was made on basis of simulation. Simulation results of semi-active suspension were compared to simulation results of adaptive suspension which contained F-v characteristics of damper used in downhill bike. MR damper with Skyhook had better results in field of riding comfort and it retained adhesion of adaptive damper. Final range of forces for MR damper in possible to use for more tests or for design of MR damper for fork of mountain bike.

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.
