Control Systems of Gears Changing on Load in Tractors Gearboxes
Holub, Přemysl ; Svída, David (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is interested in the overview of tractor’s gearboxes, which are changing on load. There are reasons, why it has to be costructed and there are requirements for it. There are also described PowerShifts, which allow us gear changing on load. After basic description of concrete gearbox, there is always some example of using in current tractors. In period named Mechanical gearboxes, wchich are changing partly on load there is more space for Zetor tractors and its gearboxes. In one of the last period there is important part about continuously variable transmissions where the driving speed is regulated steplessly. These gearboxes are considered to be modern technology of transfer engine torque.

Computational Simulations in Automotive Safety
Krkoška, Kamil ; Svída, David (referee) ; Ramík, Pavel (advisor)
The goal of this bachelor thesis is to build up a compact overview of recent development in automotive safety, concrete methods and results reached in this branch. Here are briefly described solutions for improvement of active and passive safety and next is explained testing of these systems in crash tests and assessment of these tests by using biomechanical limits. Attention is also given to the usage and benefit of computational simulations. Next are described procedures of simulations and also software used for these simulations. Then there are mentioned examples of successful applications of computational simulations.

Piston of 4-storke supercharged SI-engine for passenger car
Procházka, Miloslav ; Dundálek, Radim (referee) ; Svída, David (advisor)
This thesis is engaged in a design of basic dimension of four-stroke four- cylinder DI (direkt injection) petrol engine. It is also engaged in a design of basic dimension of crank mechanism and in a design of piston dimension. Next suggestion is related to dangerous section check. The sequential multipoint injection and boosting will be supposed for the suggestion calculation. Part of this thesis is focused on the engine development and a piston cluster detail description.

Piston for 66kW 4-stroke CI-engine
Mikulka, Václav ; Dundálek, Radim (referee) ; Svída, David (advisor)
The content of this baccalaureate work is to make computational proposal and constructional design of the four-stroke diesel engine piston. At the beginning it shortly describes the piston as a part of a piston assembly, basic constructional design of pistons for diesel engines, piston material and the way of production. Further there is a proposal of basic engine dimensions and the crank mechanism. Then there is an elaborated piston dimension on the basis of empirical data. At the end of the work there is a calculation of critical piston cross-sections calculated according to given process of the indicator diagram and designed kinematics of crank mechanism.

Piston for 373kW 4-stroke SI-engine
Kovář, Pavel ; Svída, David (referee) ; Dundálek, Radim (advisor)
This bachelor work deals with the design of a piston for 373 kW 4-stroke SI-engine. The work is focused to main dimensions of the piston, to make it able to work in difficult conditions, which is exposed at cylinder. One of the most important part of design piston is strength calculation.
