Vehicle Testing on Four Post Test Rig
Egorov, Artemii ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
The object of this master thesis is testing of vehicle using four post rig. The main goal is to make a research about testing and tuning vehicle characteristics on four post rig in order to implement them for testing of TU Brno Racing’s Formula Student racecar. The main method of testing, input signals and measurement description are presented in this thesis. The different methods of analysis of testing data to find best tuning of damper and spring stiffness for different race disciplines are described. In the last part of this work, quarter car model and multibody model in MSC Adams Car is created. Input parameters of model are based on measurements from real car/ component testing, including damper characteristics and static tire radial stiffness for best fit with the characteristics of real vehicle. The measurements themselves were also described in separate chapter of this thesis. The last but not the least goal was to compare these simulations with measurements, made od real four post rig in order to decide whether car model is suitable for racecar development.

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.
