Lifetime Prediction of the Welded Ribbed Generator Shaft
Ryšánek, Michal ; Pokorný, Pavel (referee) ; Majer, Zdeněk (advisor)
This master thesis deals primarily with the prediction of fatigue life of welded ribbed shaft. Recommendations taken from the International Institute of Welding (IIW) are used to express the stress values and the fatigue life. The stress values of examined place are expressed by approach of nominal stress, structural hot spot stress and effective notch stress. Results from stress-strain analysis are combined together with fatigue strength curves for prediction of the fatigue life. At the end of the analysis, the predicted fatigue life is compared with design life of welded ribbed shaft.

Strength design and deformation analysis of the truss construction.
Ryšánek, Michal ; Nedělka, Pavel (referee) ; Vrbka, Jan (advisor)
This Bachelor thesis is focused on strength design and strain-stress analysis of truss construction. Simplified as a plain truss construction. One of the main goals of this thesis is calculate stresses for each member of the construction, depending on the load position. The cross section of beams were designed respecting safety conditions. The influence of the gravity field was not taken into account.
