Simulation of Noise Emitted by a Single-stage Gearbox
Motl, Daniel ; Hadaš, Zdeněk (referee) ; Lošák, Petr (advisor)
The level of noise and vibration of gearboxes is one of the most important parameters for today´s customers. This thesis deals with mathematical acoustic behavior modelling and its contribution to the gearbox design using finite element method. The process is presented at three computations models. Two of those were validated with experimental measurement. Acoustic analysis were performed with software FFT ACTRAN.

Chrudim Station Redevelopment
Filo, Martin ; Motl, Daniel (referee) ; Říha, Tomáš (advisor)
The subject of the diploma thesis is to design a redevelopment of railway station Chrudim in order to meet current legislation on access of persons with reduced mobility. Two platforms with the platform edge height of 550 millimetres above the top of the rail have been designed. The amount of four running tracks through the station remains unchanged. Furthermore, the railway superstructure, railway substructure and the new drainage system was also designed.

Comparison of Open Line Track Procedures of Works
Svrček, David ; Motl, Daniel (referee) ; Svoboda, Richard (advisor)
This diploma thesis is focused on design and comparison of open line track procedures of work between stations Hranice na Moravě město and Hustopeče nad Bečvou. Subject is reconstruction of railway superstructure and substructure in kilometrage 7,785 598 to 15,016 545 (except section 8,173 463 to 8,700 000) of track n°1. The target of the thesis is to optimize open line track procedures by variation of technologies and mechanization.

Materials for atypical constructions of bicycle frames
Motl, Daniel ; Věchet, Stanislav (referee) ; Němec, Karel (advisor)
Bachelor’s thesis deals with materials for atypical bicycle frames. At first goes to history of generally bicycles. After gives definition what atypical bicycle is and includes four practical examples this type of bicycle which was real manufactured. Next step is about materials. Firstly about all types of materials uses in bicycles industry. Secondly the most suitable materials for atypical frames were choosen. In the end this materials were described in detail.
