Electronically Controlled Anti-roll Bar
Drozd, David ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
The topic of this master’s thesis is electronically controlled anti-roll bar. The first part describes the effect of body roll and anti-roll bars on vehicle characteristics, as well as an overview of currently used systems for active stabilization. The second part analyzes simulations of various driving scenarios in a multibody software in order to evaluate the effect of anti-roll bars with various stiffness on driving characteristics of vehicles. The numerical data obtained from simulations are applied in later part of the thesis. The design concept of an active stabilization system is explained in the third part. In the last part, the effect of key parameters on the performance of the system is determined.

Measurement of torsion bars and stabilizers
Bláha, David ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis deals with the measurement of the anti-roll bar characteristics. The target of this thesis is to design a device for measuring of torsional stiffness of the automobile stabilizer bars, design a measuring sequence for detection values subsequently used to calculate the stiffness, and calculate the total measuring error. The measuring device is designed for the needs of the Institute of Automotive Engineering of FME BUT.

Formula Student Anti Roll Bar System Design
Urban, Marek ; Janoušek, Michal (referee) ; Ramík, Pavel (advisor)
This bachelor’s thesis is focused on design of rear anti roll bar system of single-seated Formula student car. It is a concept with torsional bar and third damper used for example in Formula 1. Design is partially inspired by topology optimization. The emphasis is on optimization using finite element method to achieve desired stiffness at low weight. Optimization is done in series of static analysis iterations of individual parts and of the whole system in several driving states. Design of front anti roll bar system with adjustable blades is made along with front third rocker system.
