Design of frame of recumbent bicycle
Gayer, Tomáš ; Maňas, Pavel (referee) ; Vrbka, Martin (advisor)
The aim of this diploma thesis is evolution of the new model of tricycle. This thesis describes process of engineering from design of several parts and whole frame in CAD system Autodesk Inventor, to creating complete drawing documentation. Next part of this thesis is focused on basic static-structural analysis using finite element method in software ANSYS Workbench and determining boundary conditions for this analysis. The final part is about visualization of the new tricycle.

Stress, deformation and safety analysis of the tandem trike frame
Tatalák, Adam ; Gayer, Tomáš (referee) ; Vrbka, Jan (advisor)
The bachelor’s thesis contains stress, deformation and safety analysis of the tandem trike frame of company AZUB. In the theoretical introduction is short introduction with alternative cycling. The beam assumptions are analysed and computational model of the frame is made. The entire calculation is focused on three typical load states – standstill (uniform rectilinear motion), deceleration and turn transit. The progress of inner stress resultants , tension and safety in critical point of construction are calculated. Deformation of the frame is solved for standstill, which is expressed by the shift center of gravity of the rider. For analytic calculation was used MATLAB software. Model of the trike is created in Autodesk Inventor.

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.

Chassis of three-wheel electromobile
Švec, Jan ; Ramík, Pavel (referee) ; Píštěk, Václav (advisor)
The target of this thesis was to design conception of electric three-wheeler. The first chapter compares city cars and its technical data. The second chapter is focused on conception of vehicle and in the third chapter are described construction groups of vehicle. Next is here solution of stability and front suspension.

Design of Motor Three-wheeler (Auto Ricksha)
Žemla, Vlastimil ; Paliatka, Peter (referee) ; Rajlich, Jan (advisor)
The purpose of this thesis is to design a motorized three wheeler used for the transport of people and goods. The result of this work should offer an alternative to today‘s three wheelers. Nowadays, the market with three wheelers is no longer dynamic and it is in need of innovation. This work aims to respect the history of the vehicle and its traditional use along with trends in automotive design. Resulting design will become a representation of a new way this type of cheap vehicle could evolve.

HPV
Šmak, Petr ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
Design of frame of a human powered vehicle (HPV) is the aim of this diploma thesis. Wide analysis precedes design process. The thesis describes historical developement of land transportation, especially history of cycling, bicycles and other human povered vehicles, which are not so extended. Preferences and deficiencies of transportation by these ecological vehicles are shown. The thesis includes summary of most widespread and best-known conceptions, including their advantages and disadvanteges. Conception of three-wheeled vehicle was selected. It has two steered front wheels and one powered rear wheel. The accent is putted on wide efficiency, ergonomics, simplicity of vehicle`s frame and possibility of using common cycling components. 3D model of frame and assembly of vehicle was created. This model was checked by FEM computation.
