Dynamic analysis of oscillations with multiple degrees of freedom
Schulmeister, Jiří ; Houfek, Lubomír (referee) ; Březina, Lukáš (advisor)
This thesis is dealing with analysis of oscillating with multiple degrees of freedom and with example of dynamic behavior of system with two degrees of freedom with different input signals for purposes of dynamic lessons. Conventional method of making equations of motion by Lagrange’s method and their consecutive analysis is inscribed in the work. As example of system with two degrees of freedom is chosen quarter car model. Responses to different input signals are shown for the model. It is made in MATLAB/SIMULINK.

On-road Diagnostic of Vehicle Damper
Vaněk, Vojtěch ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
The diploma thesis deals with the analysis of the effects of shock absorber wear on the driving dynamics of the vehicle. Furthermore, a quarter model of the car was created in the Simulink software, where a procedure for evaluating the condition of the shock absorber while driving the vehicle was created. This procedure was subsequently validated on real measured data from the Hummer H3 car.

Regenerative Shock Absorber
Jirků, Filip ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
When car is driven on bumpy road, then suspension is continuously vibrating. Energy of vibration is absorbed by shock absorber, which improves comfort and car handling. Thesis is investigating possibility of using vibration energy to gain elektricity on designed concept.

Computational Analysis of Electric Car Ride
Procházka, Vojtěch ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
The topic of bachelor thesis is the suspension of electric vehicles and its comparison with conventional cars. The research part describes properties of electric vehicles and their influence on the design. The increase in their total weight due to batteries and chassis solutions is being investigated especially. The next section is focused on electric motors, especially electric in-wheel motors, which represent a significant increase in unsprung mass. The next chapter describes the effect of suspension and its importance in terms of driving comfort and safety. In the computational part, the influence of the increased sprung and unsprung masses, which were defined in the search, is analyzed using the quarter car model in the MATLAB program. These results are evaluated in conclusion.
