Deformation, stress and safety analysis of the bicycle frame.
Ondrejka, Jan ; Vosynek, Petr (referee) ; Vrbka, Jan (advisor)
The aim of this bachelor thesis is to assess complience and safety of the bicycle frame with basic elasticity approach, namely by deformation and stress analysis. After model simplyfying, two different cases were made. Difference between these two were in loads aplied on the frame. Maple 12.0 softwarre was used for calculation, Autodesk Inventor and AutoCAD were used for sketches. The results were checked with ANSYS Workbench.

Stress, deformation and safety analysis of the tandem bicycle frame
Profota, Martin ; Dobeš, Martin (referee) ; Vrbka, Jan (advisor)
Purpose of this work was the evaluation safety and pliancy of the frame structure tandem bicycle using method of basic elasticity with the help of the deformation and stress analysis. After introduction material and geometry of the frame tandem bicycle introductory part is focused on theoretical basis of calculation like beam assumptions, definition the beam, limit states, Sentence of Castigliano and Saint Venant's Principle. Before commencement actual analytical solution the spatial task was transferred to plane task and used model was simplified. Calculation related to two load states differing by way of load of frame tandem bicycle. For each load modes comparison with numerical solution by FEM was enabled. Mathematical software like Mathcad 14 and Maple 13 were used to analytical calculation. Check was performed by numerical solution in program ANSYS Workbench 14.5.

Stress, deformation and strength analysis of the frontal recumbend axle
Valenda, Jakub ; Gayer, Tomáš (referee) ; Vrbka, Jan (advisor)
The bachelor’s thesis is focused on evaluation of tenseness and safety of a recumbert bike's front axle using method of basic elasticity. Calculation is limited to three options that differ in manner of frame's load. Used model of the axle is beam with two straight and one curved part. A bend and twist are considered as dominant stress. In conclusion there is for each load status evaluated the progress of tension on a beam's length, safety in critical point and deformation in point of power effect on axle. In my bachelor thesis there was used Matlab software for analytic calculation. Ancillary drawings were created in AutoCAD and Autodesk Inventor.

Stress and strength analysis of the bike frame and compliance assessment at selected construction places.
Prášil, Jiří ; Horníková, Jana (referee) ; Vrbka, Jan (advisor)
Purpose of this work was the realization of stress and strenght analysis of the bike frame with the help of the basic elasticity approach. At first I had to transfer this task from three-dimensional to two-dimensional and also to simplify to fulfill the beam conditions. I also focused on static safety of the construction. This static safety was solved for two loading modes. First one was define as the load, which cyclist can induce, when he is going on the direct road. Second one was defined as the load, which he can induce, when he is going up to the hill. I used for these calculations mathematical software such as Mathcad 14 or Maple 12, but also modeling software especially Autocad for establishing correct dimensions. At the end I checked the stress and strain analysis obtained by the basic elasticity approach with the solution performed making use of the ANSYS software code.
