Modification of the WT10 aircraft for the fixed landing gear according to the CS-23 requirements
Kubiena, Jaromír ; Juračka, Jaroslav (referee) ; Vaněk, František (advisor)
In this thesis, we deal with the design of a shock absorber variant for the type of main landing gear design of the aircraft WT10 Advantic. Then we focus on the design of the selected variant of the main landing gear. Next, we follow regulation CS-23 demands to calculate the load cases for the selected main lending gear. Then we design shock absorber based on the load during landing. We compile the equation of motion of the aircraft, which describes motion of the aircraft during landing, then we compute the equation. Finally, we focus on a stress analysis of the main landing gear and the shock absorber.

GUI for Automotive Tester
Bilík, Šimon ; Čala, Martin (referee) ; Beneš, Petr (advisor)
This thesis is aiming in problematic of shock absorber testing, namely by resonance adhesive test methodology EUSAMA. The goal of the thesis was to make a program for measuring and processing signals from shock absorber tester with a graphical user interface to operate of this program. The program was written in the LabVIEW programing language and for data acquisition was used acquisition hardware of the company National Instruments.

Vehicle Multibody Model - Ride Comfort Evaluation
Friedl, Michal ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
This master’s thesis is concerned of ride comfort. It uses MBS simulation software MSC Adams, especially its Car module. It contains simulations of ride over the road with obstacles that represent the everyday conditions in real traffic. The main area of focus is to find acceleration data that are present on the driver’s seat and co-driver’s seat in relation on specific suspension settings which affect the ride comfort.

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.

Virtual model of resonance adhesion test (EUSAMA)
Hortová, Petra ; Dočkal, Aleš (referee) ; Mazůrek, Ivan (advisor)
Thesis deals with problems about areas of a non-assembling diagnostics namely resonant adhesive tester according to an EUSAMA methodology. Result of the methodology is a technical condition examination of dampers. However with regard to testing of whole suspension and damping vehicle system are results distorted by influence of testing conditons and another vehical components. Goal of thesis is analysis limits of practical use resonant adhesive tester for a quality checking of mount wheels damping. Problems are solved by a virtual simulation in a program Adams/View where is created a real model of vehical axle of Skoda Roomster TDI 1.4. In the model is consequently simulated possible functional characteristics and abrasions of single components which influence the methodology. Virtual model will be using for research activity of Institute of machine and industrial design Faculty of mechanical ingeneering Brno University of technology.

Computational models of shock absorbers of plastic and hyperelastic materials
Burdík, Martin ; Vlach, Radek (referee) ; Burša, Jiří (advisor)
An aim of the given thesis is creating of a computational model of strain-stress behaviour of shock absorbers made of plastic and hyperelastic material. First step is get ecquaint with theory of large strains, theory of hyperelasticity and plasticity. Next step is get ecquaint with options of commercial programs based on MKP. Based on this knowledge, models of simple shock absorber are made. With created models, crash tests are simulated and property of shock absorbers are compared.

Adjustable dampers of road vehicles
Šplíchal, Bohuslav ; Hejtmánek, Petr (referee) ; Vančura, Jan (advisor)
This bachelor thesis deals with the distribution and description of the activities of conventional and adjustable shock absorbers of road vehicles. It describes the dynamic of the vehicle in the vertical oscillation and the effect of damping and springs to vehicle behavior. It also describes and classifies individual suspension systems that use adjustable shock absorbers.
