Stress - strain study fo tractor body
Šnejdar, Radim ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This master thesis deals with the creation of a computational model of the load bearing part of the tractor and the subsequent implementation of the stress – strain analysis. In terms of critical working conditions, it is focused on three different load cases. Based on the results of the numerical simulation, the optimization of key components is further proposed. Modifications of the model and individual simulations of the operating conditions of the tractor body are performed in the Ansys program. Finally, an evaluation of the results, including their comparison, is made.

Friction measuring of human joints
Šnejdar, Radim ; Ranuša, Matúš (referee) ; Čípek, Pavel (advisor)
This bachelor thesis concerns about the tribology of real joints. The aim of this work is an elucidation of the influence of chosen operating conditions on shear force coefficient. It deals especially about speed, strain and rehydration. The experimental tasks will be realized on tribometer, which is available in laboratories of ÚK. In this work, current state of knowledge in the area of discussed issues are described. Also the device and measured methods which help to measure and evaluate data files. In the last section of this work, the results are evaluated and the following conclusions are established.
