Conversion of Car Front Suspension
Chaura, Václav ; Porteš, Petr (referee) ; Hejtmánek, Petr (advisor)
This diploma thesis is focused on the design of the conversion of the car front suspension for racing purpose. Existing suspension solution is described by analyse static and kinematic quantities. Furthermore, a change of suspension is proposed to improve the driving characteristics of the vehicle, where the kinematic, dynamic and strength analysis of the newly designed suspension is performed. The conclusion summarizes the comparison of the original and the new suspension design.

Design of formula SAE front axle
Honzík, Tomáš ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
My thesis will be aimed at front axle design. I am going to design the assembly of the front axle in the program ADAMS by MSC. I am going to observe and record most of cinematic changes of the car such as change of position of vehicle roll centre ,wheel camber, geometry adjustment , wheel toe-in measuring and other necessary data. The final report is going to include strength calculation of particular axle parts. I am also going to solve the axle stabilizer including strength calculation.

Design and realization of odometry sensors for mobile robot with Ackermann steering
Porteš, Petr ; Věchet, Stanislav (referee) ; Hrbáček, Jan (advisor)
Aim of this thesis is to design and construct odometric sensors for a mobile robot with Ackermann steering Bender 2 and to design a mathematical model which would evaluate the the trajectory of the robot using measured data of these sensors. The first part summarizes theoretical knowledge, while the second, the practical part, describes the design of the front axle, the design and the operating software of the front encoders and the odometric models. The last part deals with the processing and evaluation of the measured data.

Design of Hydrostatic Steering Circuit for Maxterra Tractor
Vodák, Lubomír ; Rylich, Jan (referee) ; Dundálek, Radim (advisor)
Theme of this diploma thesis is a design of a hydrostatic steering circuit of the Maxterra tractor, where the working medium is oil from the gearbox. Part of the design is also check calculation of the hydrostatic circuit of the steering. Next part is also the design of the steering column. The circuit of the hydrostatic steering and the steering column will be used on the new Zetor Maxterra tractor.

Stress, deformation and safety analysis of the recumbent bicycle frontal composite axle
Ondrejka, Jan ; Majer, Zdeněk (referee) ; Vrbka, Jan (advisor)
This diploma thesis deals with creation of computational model of AZUB recumbent tricycle composite axle for stress strain analysis. The thesis consists of four main parts. The first part contains introduction to the offer of full suspended tricycles from the most known manufacturers. Furthermore it contains introduction to composite materials that makes the main element of AZUB´´s suspension, and the description of the AZUB´´s front axle. In the second part there is detailed compilation of computational model for purpose of stress strain analysis of three load states. The effect of specific material and geometry parameters on axle behavior is discussed with the aim of choosing the most appropriate variant. Third part deals with the manufacturing of the front axle prototype and with tests leading to input data for numerical model and verification of computational model. Modifications and changes that lead to manufacturing of the second prototype are content of the last part. Based on this experience some recommendations for future development of the numerical axle model and the front axle suspension itself are formulated.

Electric Off-road Vehicle for Children Axles
Dlouhý, Filip ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
The diploma thesis deals with the design of the chassis structure for an electric off-road vehicle of the crosskart type. In the first part, the research part of the sub-components that are used for the construction of these vehicles is briefly mentioned, including their aspects that must be known when designing the vehicle. The second part describes the actual design of the front and rear axle structure, which was optimized in the program Adams Car and then a model was created in the program Solidworks. The entire design of the chassis was constructed with the intention of assembling the chassis from commonly available components that are currently on the market.

Design of an Electric Velomobile
Starý, Ondřej ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
The aim of this diploma thesis is the design of an electric velomobile, more precisely its front axle and bodywork, as one of the possible alternatives to cars for cities. First, a research analysis of the available electric velomobiles is carried out. In the next step, which is the design of the electric velomobile itself, the parameters and characteristics of the vehicle are determined. The design of the front axle is based on these. The design and optimization of the suspension geometry, its calculation, steering, and their construction design solutions are carried out here. At the end, the design of the bodywork is made.
