Study of mobile sailing yacht crane
Rozsíval, Jan ; Škopán, Miroslav (referee) ; Pokorný, Přemysl (advisor)
The work contains a functional calculation of the lifting device, structural design and strength control of the supporting structure of the crane in accordance with the specified parameters. Part of the bachelor's thesis is a partial drawing documentation.
Motorcycle rotary engine
Novotný, Petr ; Rozsíval, Jan (referee) ; Zháňal, Lubor (advisor)
Diploma thesis is focused on conceptual design of Wankel rotary engine with performance between 30-60 kW. Performance of designed engine is determined to 35 kW and volume of one chamber amounts to 245,58 cm^3. In this thesis are step by step calculated geometrical properties of each design group which are afterwards put into 3D data. There is also solved cooling system of designed engine and design of geometrical and characteristic properties of parts of cooling system. Last but, not least there is solved placement of designed engine into frame of motorcycle. As suitable motorcycle has been chosen Honda CBR125R because it has very advantageous layout of frame.
Aerodynamic design of heavy commercial vehicles
Šuľak, Andrej ; Rozsíval, Jan (referee) ; Fojtášek, Jan (advisor)
This bachelor's thesis deals with the currently available aerodynamic drag reduction devices for articulated and drawbar trucks. The main goal is to reveal the given topic to the reader, beginning with some basic information about aerodynamics and then explaining how these drag reduction devices work. They often provide additional benefits apart from improving aerodynamic efficiency.
Design of Device for Tyre Parameters Measurement
Pacut, Patrik ; Rozsíval, Jan (referee) ; Hejtmánek, Petr (advisor)
The aim of this thesis is a method selection and design of measuring device for experimental identification of directional tire characteristics for passenger cars. The first part analyse directional characteristic and method of measurement. The next part focuses on the design of the measuring trailer and selecting measuring equipment with description.
Children Terrain Electric Vehicle
Sedlář, Martin ; Rozsíval, Jan (referee) ; Blaťák, Ondřej (advisor)
The master’s thesis is focused on a conceptual design of a children terrain vehicle with electric drive. At the first part there are described children terrain vehicles rules, electric drives, regulations for a frame test and types of suspension. Then a suitable electric engine, an accumulator and other important parts of the vehicle are chosen. The following part describes the frame construction and its stress-strain analysis using Finite element method. The last part of thesis describes the suspension construction and front suspension kinematics solved in a multibody software. The result of thesis is a vehicle conceptual design created in CAD software Creo, supported by results of the stress-strain and kinematic analysis.
Chassis Torsional Stiffness Measurement Stand
Kudr, Jan ; Rozsíval, Jan (referee) ; Blaťák, Ondřej (advisor)
Those theses describe torsional stiffness car chassis. Here is write short knowledge about various type of measuring, explain impact torsional stiffness on car handling. Target of this theses is work out structural proposal of device for measuring torsional stiffness car chassis, suitable method of measuring, calculate measurement mistake and provisional cost calculation.
The utilization of reverse engineering in computation of vehicle aerodynamics
Rozsíval, Jan ; Forman, Matěj (referee) ; Porteš, Petr (advisor)
The vehicle body was measured by using ATOS 3D scanner. Measured data from the ATOS 3D scanner were applied to make a 3D model of vehicle body and to make a 3D model of whole vehicle by using computer program Pro/ENGINEER. The model of vehicle was made with a view for future use of CAD model. Surface of the vehicle model was used for computation of vehicle aerodynamics – aerodynamic static pressure distribution by using CFD software Star-CCM+.
Driving safety systems
Rektořík, Jiří ; Rozsíval, Jan (referee) ; Suchý, Jan (advisor)
Bachelor thesis is focused on the description and measurement of characteristic variables that affects driving comfort. Driving comfort is closely related to driving safety. This thesis deals with measured quantities but also deals with comfort in the cab and optimally adjusting elements in the cab.
