Optimalizace rozměrů základového rámu formy na velké odlitky / Optimization of dimensions of the base frame to form for large castings

Mottl, Jan January 2011 (has links)
In this thesis the problem of optimizing the dimensions of the base frame molds for casts with FEM and for 4 weight classes, ie casts weighting 1, 3, 5 and 10 tons is solved. For the evaluation of the FEM ANSYS program was used. There are gradually presented optimization procedures for all four weight classes. There was established the persistence of forms and frame and at the end the conclusion of the technical-economic evaluation of the proposed forms in terms of material savings in comparison to the current state of production was made.

Návrh přední části rámu vozidla Formule Student / Formula Student Front Chassis Part Design

Lhota, Martin January 2011 (has links)
Martin Lhota Formula Student Front Chassis Part Design DW, IAE, 2011, 75 pp, 62 pics The aim of the thesis is to suggest a suitable configuration of Formula Student Car’s front part of a frame according to current rules of SAE organization in the Formula Student competition. In this proposal low weight, manufacturability and sufficient torsion rigidity were preferred, whereas previously suggested solutions were reflected. At first there is presented a list of important SAE rules for the construction of front part followed by a short recherché of development of the constructional solution of frames and frames suitable for Formula Students car. Secondly there is described process during frame construction design and its computational model for the analysis which simulates torsion with the support of MKP system. Gained results and some parameters of the frame are compared with similar version of the frame construction which was suggested and made for the first Formula Student Car of our University. Moreover, there is also presented summary of suggested frame and also recommendation with possible alternatives for the next development.

Konstrukce multifunkčního obráběcího centra / Design of multi-functional machining centre

Gruník, Jan January 2011 (has links)
This work deals with the construction and describes a detailed calculation of a machine frame of the shaft-turning lathe and 2D axis passes including the underpass according to the chosen initial parameters. The information contained in this work is not only of theoretical knowledge, but it should also serve for the practical use as a guide for the frames construction. The work also contains a background research on the topic, the model frame, the frame strength analysis, optimization of the frame, 2D axis, calculation, design and implementation of the underpass and the whole assembly. A suggestion for the future procedure and optimizing of the existing structure is found in this work as well.

Návrh pneumobilu s pneumatickým pohonem / Design of pneumobil driven by pneumatic motor

Podhorský, Petr January 2011 (has links)
Master thesis deals with design of "student" pneumatic car equipped by pneumatic elements of a chosen firm. The introductory part is devoted to mapping the Hungarian competition. The idea of designing such vehicles comes from this competition. Next step is analysis of vehicles that are present in this competition. The main part describes the development of vehicle from the initial design, through analysis of main components, through to the production and presentation. The work contains a strain-stress analysis of the frame which is made by using the finite element method. The work ends with the conclusion which assesses the results.

Rám pro výtahový stroj / Frame for elevator machine

Sokol, Filip January 2011 (has links)
The diploma thesis deals with replacement of frame for elevator machine. Original frame was made from metallurgic profile and was replaced by bending sheet metal. The thesis contains strength analysis and calculation of original construction solution as well as the new one. Strength calculation was done in program I-DEAS for two load sets: full load in regular operation and immediate cessation of elevator machine in full speed.

Baja SAE Vehicle Design / Návrh vozidla Baja SAE

Hajdušek, Zdeněk January 2012 (has links)
This master’s thesis describes the design of the Baja SAE vehicle according to the applicable rules. In the beginning is the work focused on search competing vehicles and subsequently on design the first Baja SAE vehicle in the Czech republic. This thesis is systematically divided into chapters according process to the vehicle design. The main part of a master's thesis is design of axle kinematics in software Adams and frame design. The model was designed in Catia V5. The frame was analysed of torsional stiffness and stress in software ANSYS.

Koncepční návrh autocrossového vozidla pro děti s objemem motoru 150 ccm / Children Autocross Buggy with 150 ccm Engine Conceptual Design

Rada, Lubomír January 2012 (has links)
This master´s thesis descripe the conceptual design of children´s kartcross vehicle. According to the specification, I focused on design of frame, the calculation of the torsional stiffness and axle kinematic. I was inspired by modern trends kartcross vehicles. 3D model is designed in Pro/engineer. Torsional stiffness was counted using FEM software ANSYS 12.1. Finally the design and calculation of front suspension was done in MBS software Adams.

Thorž, František January 2013 (has links)
This diploma thesis deals with an alternative frame design of Formula Student which is made of aluminium honeycomb sandwich. First part describes the current options analysis, the property of aluminium panel and its loading behaviour. Next part provides a frame design and computational model for stress analysis by FEM and the main part is contains the calculation of torsional rigidity including its procedure. Finally, the thesis provides the comparison with tubular space frame of the 3th generation formula Dragon.

Návrh vozidla skupiny E2 pro závody do vrchu / Design of the Group E2 Vehicle for the Hill Climb

Malchárek, Martin January 2013 (has links)
This diploma thesis describes the design of the E2 hill climb car and it is design by following the FIA rules. Next parts are focused on detailed design of the front and rear suspension and design of the frame. Diploma thesis is processed using CAD system Autodesk Inventor 2011, in which was created all sketches and models. The suspension geometry during bound and rebound movement of the wheel was made in MBS system MSC Adams 2010. FEM analysis of the frame was made in ANSYS Workbench 12.1.
