The Axles of SxS Vehicles
Štolpa, Radek ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
The diploma thesis deals primarily with the topic of the kinematics of the wheel suspension that has a significant effect on the dynamics of the whole vehicle. The thesis gives a general overview of kinematic characteristics and their impact on driving characteristics. It deals with load transfers that occur due to lateral and longitudinal accelerations. The thesis analyses the axles of the SxS vehicle, which has wheel strokes up to 600 mm. The axles have high requirements for changes in kinematic characteristics. The thesis provides an overview of the used axles and then compares them with the original ones. The thesis contains its design of axles with the procedure and evaluation of differences compared to the other axles specified by the boundary conditions. An algorithm using analytical geometry was also created where instant centre positions, roll centres and anti-characteristics for the static position of the vehicle can be calculated. In conclusion, it contains a sensitivity analysis, which aims to acquaint with the effects of kinematic connections of double wishbone suspensions on the kinematic characteristics.

Effect of Suspension Kinematics on Vehicle Handling
Trnková, Lucie ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This diploma thesis deals with effect of suspension kinematics on vehicle handling. In the first part of the thesis, there are the basic parameters of suspension kinematics introduced. In order to perform the simulations, two multi-body vehicle models are created, one of which is derived from an off-road vehicle, for which there has been a significant change in suspension. For each model, there further is a description and comparison of the kinematic characteristics of different settings variants of their suspension introduced. The main part of the thesis deals with the analysis effect of individual suspension changes on vehicle handling during the selected driving maneuvers. The results of the simulations are qualitatively and quantitatively evaluated, and the resulting findings are in the conclusion summarized.

Wheel Alignment and Kinematic Characteristics Measurement with Use of Optical Scanners Tritop and Atos
Dvořák, Martin ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
The diploma thesis is focused to possibility utilizing of optical scanners TRITOP and ATOS for set up geometry of wheels. In background research are described the most important parameters of wheel suspension and devices for measuring these parameters. Practical part is concerned with progression of measurement, results and with determination coordinates of kinematic points. These points are made 3D model of forward and backward suspension wheels. This model helps to make kinematic characteristics and its progression due to attitude of wheel. In last part is described possibility to utilizing of optical scanner ATOS to common measurement of geometry wheels.
