Passenger car with pneumatic drive
Hudec, Miroslav ; Ramík, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of this thesis is to propose a basic conception of passenger car chassis part with pneumatic drive (next only pneumobil). The pneumobil was designed mainly from BoschRexroth serial parts. The layout of this vehicle was arranged as dual-track with pneumatic drives with O 80 mm bore and stroke 125 mm. These engines are placed crossways top-down. Next I provided stress-strain analysis of rear bottom vehicle part, where act forces from rear wheels and pneumatic motor. The crucial task of this thesis is to design the chassis frame, choose suitable material and pneumatic motor for most effective usage of compressed air. The final goal is to propose an ideal gear ratio.

Anti-noise Protective Agents in Tractors
Hudec, Miroslav ; Svída, David (referee) ; Dundálek, Radim (advisor)
The aim of my bachelor´s thesis is anti-noise protective agents in tractors. In this work I focused on influence of wanted and unwanted noise to humans and the results of it. In other part I concerned with simple calculation of noise, each sources´ vibration and sound transmission of solids. These calculations are very complicated and complex but for my purpose I simplified them and used only the basic ones. The next procedure is to clear out the noise by constructional alterations, which are much-used. At the end I mentioned the used materials and where they are used for clearing out the noise. In the conclusion Ispecified some tractors´ marks and their used constructions and materials in a different parts of a tractor.
