Pykal, Vojtěch ; Nedoma, Jiří (referee) ; Kaplan, Zdeněk (advisor)
This bachelor‘s thesis deals with the issue of bicycles for seniors and city traffic with additional electric drive. The introductory part deals with the influence of movement on human health. Further development and technical analysis of bicycles. This is followed by a comprehensive analysis of pedelecs and an outline of an ideal electric bike for seniors. In conclusion, there is my evaluation of this issue.

Computational Modeling of Gear Mesh Engagement Dynamics by MBS Approach
Pykal, Vojtěch ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This master’s thesis is focused on the compilation of a computational modelling of gear mesh engagement dynamics of a spur gear by MBS approach. The user input is the specific geometry of gears, the operating speed, and the load torque. The output are the forces in the gear engagement and the reaction of the forces in the wheel bearings depending on the change in the stiffness of the gear due to the changing number of teeth in the engagement and the change in the axial distance. This model is characterized by a fast and relatively accurate calculation in the time domain. This means that it can react to changes in parameters during simulation such as axial distance, speed, and torque.
