Design of Device for Vehicle Suspension Elastokinematics Measurement
Pohořelský, Petr ; Vančura, Jan (referee) ; Hejtmánek, Petr (advisor)
In my dissertation, I was concentrated mostly on a pliability of problematic of wheel´s suspension. My thesis is mostly a detail design proposal of a device, which is determined for a measurement and record of wheels suspension system´s elastic deformation. My theoretical part of this thesis is a search of existing devices and its problematic. The other part of my dissertation is a description of individual parts of my designed device and also an analysis of designed components´ intension. My thesis includes calculation, for case of realisation. There is also a design of measuring chain, methods of results´ evaluation after measuring with this device and theoretical analysis of measurement´s inaccuracy.

Rear cover hinge design of car
Bílek, Vojtěch ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
The thesis deals with the issue of suspension of the 5th passenger car door. The introductory part deals with the possibilities of mounting the 5th passenger car door. In the next part, a HDS hinge was selected, which is further solved using a numerical and experimental method. Aluminium alloy was used on this HDS hinge to reduce weight. In the first step, a technical experiment was performed on the existing state (steel) and a strain-strain analysis was performed. Based on the stress-strain analysis of the material change variant without structural change, unsatisfactory results were obtained. After that, design changes were proposed such as increasing the thickness of the tube wall in the Creo program, and this variant was also subjected to a stress-strain analysis using the numerical modelling. Comparison of the results was based on the values of elastic deformation and equivalent stress. Finally, the thesis dealt with the manufacturability of the proposed component within which, a technical experiment was carried out.
