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.
Reconstruction of Track Section Hanušovice - Jeseník in 36,65 - 30,9 Section with Technological Procedure of Works Design
Prikner, Pavel ; Motl, Daniel (referee) ; Svoboda, Richard (advisor)
The aim of the bachelor thesis is to design a reconstruction of a track railway Hanušovice – Jeseník in the track section of km 26,65 – 30,9. The thesis includes modification of the track geometry parameters, reconstruction of the railway superstructure and track substructure. The proposal deals with rail crossing in accordance with current legislation. In this thesis is proposed renewal of drainage and technological procedure of works design.
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.
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.
Reconstruction of Track Section Stará Paka-Trutnov in 118,9 -121,6 Section with Design of Technological Procedure of Works
Maixner, Pavel ; Motl, Daniel (referee) ; Svoboda, Richard (advisor)
The objective of my bachelors thesis is the reconstruction of single-line railway track Stará Paka - Trutnov in 118,9-121,6 track section. Desing of track geometry parameters and permanent way assembly is the main part of this work. Solve problems with railway crossings is necessary during the reconstruction. Drainage system and technological procedure of works are designed too.
