The thesis consists of rear wheel suspension design for light Formula Student racing car, especially design of upright, wheel hub and other parts of the assembly. Design was done in CAD software PTC Creo 2.0. Thesis also mentions calculation of critical wheel loads, wheel bearing life calculation and wheel loads during the race as well as stress analysis in Ansys Workbench and fatigue life analysis.
Formula Student Rear Wheel Carrier
Novák, Pavel ; Svída, David (referee) ; Ramík, Pavel (advisor)
The aim of this thesis is to create a design rear upright for a racing Formula Student category car. It is necessary to propose a design group of the rear wheel assembly with the upright with all requirements related thereto, for example solutions camber settings. Everything is modeled using the CAD system. There is developed computational model which is placed in ballast states of strain and stress analysis by finite element method. There is also designed a suitable material for the production of the rear upright which is optimized. The conclusion deals with the inclusion of the proposed arrangement in the overall vehicle assembly and is concluded with evaluation and suitability of the proposed solution.
Formula Car Front Wheel Carrier Simulation Analysis
Gach, Jakub ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
This Master’s thesis is focused on the suspension of the front wheel, more accurately for specific part, upright. It describes the basic requirements for construction, distribution of uprights, their method of production and types of materials used. It briefly mentions topology optimization and its two optimization methods. Also deals with vehicle dynamics for driving conditions – standing vehicle, braking and cornering. In the practical part, the work is focused on determining the load effects on the upright during the aforementioned driving conditions using MBS software. At the end of the work, FEM stress and deformation analyses are performed for loading on the wheel side and on the suspension side, which are then compared and evaluated.
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.
Design of delivery van.
Kubík, Petr ; Paliatka, Peter (referee) ; Rubínová, Dana (advisor)
The diploma work is aimed at a complex design of a delivery van of the near future. The need for a delivery van to be used as a working tool is constantly evolving. This is namely caused by the expansion of on-line shops & the need to save on running cost of a business. The delivery van is especially designed for use in city traffic. The innovation reveals a single person cabin with panoramatic view, ecological propulsion of the vehicle and the technical solution to the suspension of wheels which allow the turning of all 4 wheels to an angle ranging from -55° to +90°. As a result the vehicle has the ability to perpendicularly drive up to a pavement, fitting in a very narrow space. In addition, it can freely drive forward or backward in a sideway direction. The loading space of the delivery van and its floor is modified as such to allow for one man manipulation, making loading & unloading of goods a simpler task.
Axle assessment using the EUSAMA methodology
Vítek, Lukáš ; Roupec, Jakub (referee) ; Mazůrek, Ivan (advisor)
This bachaleor thesis deals with optimalization of axle assessment. The introduction is directed to description shock absorber, non-assembling diagnostics and dynamics of vehicles. The automotive suspension is meant to provide comfort and mainly safety for the passengers. Because shock absorber are stressed, it must be controled. The most important kind of non-assembling diagnostics for this thesis is EUSAMA methodology. All measurement are realized with resonant adhesive tester, which is named TriTec. This device is structural simpler, then other one.
Formula Front Wheel Carrier Design Modification
Lněnička, Martin ; Svída, David (referee) ; Ramík, Pavel (advisor)
This thesis deals with the structural design of front wheel hub of Formula Student the car categories in the CAD system. It includes comparison to proposal design of the hubs, different concept of wheel-seat and wheel suspension of a formula cars and a motor-cars. There is described a few version of design front wheel carrier. The first step is proposed assembly wheel of Formula Student and the next step is realized analytic simulation a stress by FEM of the front wheel carrier and his construction modifications.
Design of an Electric Velomobile
Starý, Ondřej ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
The aim of this diploma thesis is the design of an electric velomobile, more precisely its front axle and bodywork, as one of the possible alternatives to cars for cities. First, a research analysis of the available electric velomobiles is carried out. In the next step, which is the design of the electric velomobile itself, the parameters and characteristics of the vehicle are determined. The design of the front axle is based on these. The design and optimization of the suspension geometry, its calculation, steering, and their construction design solutions are carried out here. At the end, the design of the bodywork is made.
Measurement of vehicle suspension bushing characteristics
Kopecký, Petr ; Zháňal, Lubor (referee) ; Porteš, Petr (advisor)
This master’s thesis deals with the measurement of static characteristics of wheel suspension bushings. It includes a structural design of the test device and drawings according to which the device was manufactured. The device has several variations for different stresses and is applicable with possible modifications to various bushings including the ones that do not have common axes. The measurement procedure, the results of the measurements of the static characteristics and their analysis and comparison with the finite element method calculations are also given. The measured characteristics were then added to the model of the axle for multibody simulations.
Design of Formula Student Wheel Suspensions
Urban, Marek ; Fojtášek, Jan (referee) ; Porteš, Petr (advisor)
Tato práce se se zabývá návrhem kinematiky zavěšení kol obou náprav. Na základě analýz jízdních dat, multi-body simulací v softwaru Adams Car, simulací v Matlabu a analytických kalkulací v Mathcadu, je navržena řada změn s cílem zlepšit jízdní vlastnosti vozu Formule student, tyto změny jsou následně implementovány do CAD modelu vozu. Jednotlivé změny kinematiky náprav jsou provedeny na základě analýzy konkrétního problému, který se snaží řešit. Jednou z problematik je zástavbová náročnost systému odpružení a zavěšení zadních kol, zde je cílem snížit hmotnost, výšku těžiště a moment setrvačnosti. Další problematikou je geometrie předního kola, kde je cílem zlepšit využití pneumatik a snížit síly v řízení. Dále se práce zabývá simulacemi elastokinematiky zadní nápravy, součástí je také návrh měřícího zařízení. V poslední části je zkoumán vliv provedených změn i elastokinematiky na jízdní dynamiku vozu v ustálených stavech za pomocí MM metody simulované s modelem celého vozu v Adams Car a zpracované v Matlabu.
