Formula Student Front Wheel Carrier Design
Černý, Filip ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
This thesis deals with the design of the front wheel hub and upright of Formula student car. First component is a short search on Formula Student event and comparing diverse structures of upright for use in both racing and road cars. It also includes design of hub and upright in the CAD program and computational model of the upright created in FEM program specifically for stress analysis in selected conditions. It also includes optimization of the overall proposal.

Calculation of Con-rod Stress in Multi-Body System
Malinský, Marek ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
The aim of my thesis is to create a procedure for the calculation of con rod stress in MBS Software. The thesis contains several parts, i.e. a short research of contemporary con rods, con rod modelling with the use of Pro/E, methodics of the finite-element con rod model preparation and model analysis in ANSYS Software, creating of virtual combustion engine template with flexible con rod and carrying out a strain hardening analysis in ADAM/Engine software. The theme of my thesis is quite demanding in the combination and the use of several computer software programmes. The thesis offers a survey of possibilities, procedures and methodics of con rod stress solutions that help to clarify the matter.

Interface Optimization of Welded Fuel Accumulator of Common Rail System
Hurt, Libor ; Svída, David (referee) ; Ramík, Pavel (advisor)
This master’s thesis is aimed to sphere of injection system for diesel engines. The main task of thesis was to invent new concept for high pressure interface of laser welded fuel accumulator, that would able to endure pressure 2000 bars and higher. Also, it would be applicable to serial production. Thesis includes description of diesel system by Bosch, making of design proposals in ProEngineer program and making of stress analyses for some particular elements in Ansys. Whole the work was passed in conjunction with Bosch Diesel development department.

Engineering design of the vehicle suspension rocker
Poláček, Vojtěch ; Ramík, Pavel (referee) ; Bradávka, Marek (advisor)
Diploma thesis deals with the design and stress analysis of the rocker suspension for an autocross car. The research describes some real cases of using suspension with pushrod and rocker in motorsport. Subsequently, the work deals with the design of the wheel bump/rebound limiting stops and bump/rebound measuring. The challenge is to design a component shape, size and select fit of a rocker with an emphasis on low weight whilst maintaining sufficient strength and rigidity. The design study include stress analysis which leads to optimize the final shape.

Vehicle Body Side Structure Simplified Parametric Model
Smilek, Tomáš ; Ribka, Tomáš (referee) ; Ramík, Pavel (advisor)
Simplified parametric model of vehicle side structure MT, Institute of Automotive Engineering, 2010, p. 117, fig. 130, appendices 0 This study´s motivation is based on Euro NCAP tests, especially side impact test, which consist of barrier impacting into vehicle side. Goal is to make simplified parametric model of vehicle side structure. The behavior of loads on dummy must be as identical as possible with big FEM model.

Laser Welded Rail ZnNi Coating Adhesive Strength Evaluation
Flieger, Vít ; Skrutek, Ivo (referee) ; Ramík, Pavel (advisor)
The aim of this bachelor thesis is drafting and testing of methods for evaluation of adhesive strength ZnNi coating on laser welded rail. In individual parts is descriped function of common rail system focusing on high pressure tray – rail. Then are described several methods for evaluation of adhesive strength. Theree methods are selected to testing on rail. The experimental part describe the resutls of this tests and modifications for better results. In the last is chosen one method with best results and is complied draft of specification for this method.

Formula Student Vehicle Frame Optimization
Krkoška, Kamil ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
The goal of this diploma thesis was to create optimalizated frame design for Formula Student/SAE. Basic requirements were, that new design must meet the newest Formula Student/SAE rules and other various requirements. In the thesis are built up an overview of most important rules and also an overview of previous frame designs. Next are described design process of the new frame and its stress analysis in FEM software. Main attention is given to analysis of torsional stiffness. The results of analysis are compared to previous frame designs and to parameters of Formula Ford. There are also given recommendations and other possibilities for further frame design development.

Torsional stiffness of Formula Student frame
Jurnečka, Ladislav ; Ramík, Pavel (referee) ; Porteš, Petr (advisor)
Diploma thesis deals with detection of torsional stiffness with using photogrammetric equipment TRITOP device and subsequent comparison with created computational model in FEM software. Measurement and calculations were accomplished according to tutorials, which are the most effective and giving the most accurate results. Next the optional method of measurement of torsional stiffness in practice is formed for future formula series called Dragon. The reasons of different results and suggestion of optimalization are sum up in the end of the thesis.
