Vehicle Semi-active SuspensionSystem
Salcburger, Martin ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
The aim of this diploma thesis is to design algorithms of semi-active suspension system for a quarter car model, compare their function with respect to ride comfort and drive safety. Consequently, setup control algorithms for using in the Adams software. The result of this thesis should be to determine the effect of semi-active suspension control system on vehicle behavior.

Rallye Championships and Used Engineering Including WRC Series
Novák, Pavel ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
The content of the bachelor thesis is an overview of the current condition of technics used in the car racing competitions focused on the WRC serial. The thesis is diveded into five parts. The first part introduces the contemporary car competitions and FIA federation. The second part is focused on specification of the WRC cars. The third part familiarizes with the organization process of the WRC championship. There are introduced crews with their teams and their results in the constructor cup. The main attention is given to the parts four and five which deal with the contemporary engineering used in WRC and the development trends in this field. There are given methods of virtual designing, computer simulation and testing. In the conclusion of the thesis there are mentioned examples of WRC car development and solutions assumed for the serial cars from the WRC technics.

Hydrodynamic dampers on the principle of magnetic fluid
Přikryl, Matěj ; Himr, Daniel (referee) ; Pochylý, František (advisor)
This bachelor's thesis deals with damping vibrations emerging due to the movement of a vehicle. The first section provides an overview of contemporary types of dampers with thorough explanation of the principle of hydrodynamic damper. This section also contains simulation of vibrating vehicle equipped with passive damper. Literature research of magnetic fluids and description of magnetoviscous phenomenon is presented in the second part, which freely continues to the topic of magnetorheological (MR) dampers. The final chapter firstly describes current hydrodynamic dampers based on squeeze film (SF) mode of magnetorheological fluid and at the conclusion the author's concept of SF MR damper is submitted.

Single purpose machine for automotive parts assembly
Trávníček, Ivo ; Hrbáček, Jan (referee) ; Krejsa, Jiří (advisor)
Práce se zabývá návrhem jednoúčelového plně automatického zařízení pro automobilový průmysl, které dávkuje silikonovou směs do pouzdra snímače. V první části práce je řešen návrh mechanické části zařízení, zejména manipulátoru pro polohování dávkovací hlavy. K pohonu manipulátoru je využito pneumatických prvků, které jsou řízeny elektrickými signály. Druhá část práce se zabývá řízením stroje, které je realizováno pomocí PLC systému. Obsluha může ovládat zařízení nebo sledovat aktuální stav na dotykovém panelu. V závěru práce je prezentováno skutečné provedení zařízení a propojení s výrobní linkou.

The design of the landing gear of the small two-seat airplane
Trojánek, Tomáš ; Katrňák, Tomáš (referee) ; Vaněk, František (advisor)
The aim of this master thesis is modification of landing gear for accomplishment CS-23 regula-tion from that purpose, because landing gear in the use can't pass this type of certification. The first part examines the alternatives of landing gear with consideration optimal technical and eco-nomical difficulty. After finding optimal type of landing gear with shock absorber is there part of designing and computing the load. Last part of thesis is about stress analysis of whole con-cept and reconsidering final changes.

Shock Absorber for Generating of Electrical Energy
Maťaš, Marek ; Vetiška, Jan (referee) ; Hadaš, Zdeněk (advisor)
This these is considering with possibilities of generation of electric energy, with use of linear generator in automotive industry, that linear generator is replacing shock absorber. Subsequently the base model of shock absorber is used and excited with sinus signal. From this simulations are got the results of damping and power. Then it will be made a simulation of shock absorber, with known parameters of damping, mass of vehicle and real model of road. Then it is made control with PID regulator.
