Design of production technology for the olympic bar
Bělunek, Matěj ; Trčka, Tomáš (referee) ; Varhaník, Matúš (advisor)
Goal of this bachelor thesis is to design production technology for the olympic bar. Two types od manufacturing are proposed, conventional and modernized. Conventional production is cerried out on an universal center lathe, modernization converts production to CNC lathe. The main output, besides the manufacturing design itself, is the comparison and technical-economic evaluation of the production technologies. Thesis includes documentation and technological processes.

Physical axle model for dynamic tests
Bělunek, Matěj ; Dočkal, Aleš (referee) ; Mazůrek, Ivan (advisor)
The aim of this thesis is the design of a physical axle test station, along with a virtual dynamic model, with the purpose of vehicle suspension tests. The axle, or half-car, model is the answer to the inaccuracies of the most widely utilized suspension model, and the high cost of the full vehicle testing. The motivation for the new test station and its virtual model is the prospect of accurate, quick and effortless testing and optimization of the vehicle suspension characteristics. The existing solutions in most cases substitute actual suspension elements (axle) and wheels with auxiliary parts leading to a departure from reality. The design of the new test station is based on the analysis of current physical model solutions and in accordance with set requirements. The tester substitutes the vehicle Škoda Fabia I Hatchback and utilizes its actual rear axle including suspension elements. The assembled rig, or rather its functionality, is successfully experimentally verified. The created virtual dynamic model, using ADAMS software, is identified against the designed test station, while the obtained simulation results are compared with the experiment data. Meeting the experiment predictions and virtual model results validates the tester’s ability to sufficiently reflect real car suspension behaviour and it is ready for further vehicle spring and damping properties testing.
