An analysis of motorcycle driving properties
Janovec, Ladislav ; Růžička, Bronislav (referee) ; Mazůrek, Ivan (advisor)
This thesis deals with evaluating methods of vehicle driving characteristics with focus on dumping units analytical assessment. In theoretical part thesis describes some of today analytical methods used in practice and in experimental measurement. Analytical methods allow objective evaluation in the assessment of driving characteristics. Main objective of the thesis was to formulate two independent methodical procedures for analyzing motorbike driving characteristics with the subsequent practice verification.

Electronic car suspension tester
Jeniš, Filip ; Růžička, Bronislav (referee) ; Mazůrek, Ivan (advisor)
This thesis deals with the development of a conceptually new tester for evaluation of car chassis damping. The tester will work on the basis of tracking of the body attenuation at the points of the silencers after crossing the obstacles. The kinematic motion parameters will be scanned using an inertial measurement unit.

Excitation device of the physical axle model
Zeman, Petr ; Čížek, Petr (referee) ; Mazůrek, Ivan (advisor)
The main objective of this thesis was to design an excitation device for a full-axle test station for the simulation of a crossing test over bump, used to verify the springing and damping properties of passenger car wheel suspensions. The motivation for the development of the excitation device of the all-axle station was the need to test the properties of the suspension elements in a real scale, and to add a new form of excitation for the axle model that is built in the laboratory of the IMD FME. Until now, this had only one excitation option, a vibration resonator. Firstly, a virtual dynamic axle model was created by crossing an obstacle in Matlab Simulink, which was mainly used to determine the force load exerted by the simulator. The proposed device is divided into a weighing arm and a drive unit. Using the designed device, the obstacle crossing can be simulated with a height of up to 5 cm at a speed of up to 30 km/h and an axle weight of up to 800 kg. The device also records the force exerted from the wheel to the pad throughout and after the excitation. The developed device meets the specified space and modal behaviour requirements, which does not interfere with the force measurement process. The device operates by forcing a cylindrical barrier under the axle wheel and, in conjunction with an existing axle model, forms a crossover test simulator that will be used for the development and experimental verification of automotive suspension components, such as MR dampers in particular.
