Abstract:

This diploma thesis deals with description of the design of the rear of the vehicle structure of Formula Student processed by using a 3D CAD system. Formula have to fulfill all requirements Formula Student rules. The requirements and rules are given by building of engine and other considered engine components. The final version of the design of the rear part is assembled with the supplied front and the computational model is created to simulate the torsional stiffness of the FEM system. Another analysis model is created for a foreign supplied frame construction. Both of these frames are in terms of torsional stiffness evaluated and mutually compared. There are also mentioned selected Formula Student rules and overview of the formula frames and their overview.

Abstract:

This diploma thesis deals with the design of door frame curvature, meant for rail vehicle. Flat glass is adhesively bonded onto the curved door frame and due to the elastic deformation the door frame bends backwards. Hence the door frame must be bend with reserve so that the elastic deformation is covered. Finite element analysis of currently manufactured door with constant curvatere has been carried out, with this analysis it has been checked that the chosen problem approach is suitable. Design of door frame curvature is then made for door frame with combined curvature (different for lower and upper part of door frame). The aim of this thesis was to design the curvature so that after glass is bonded onto it, the door frame will have the right dimensions.

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.

Abstract:

The aim of this work is a static analysis of the reinforced concrete frame structure loaded by the effects of seismic loading. The work deals with the solution of multi-storey reinforced concrete structure designed for common loading conditions and further for possibilities of strengthening of the structure on effect of seismic loading. In the first phase of the work, the static analysis and the design of the main load-bearing elements of the frame structure (columns and main girder) were carried out for the ultimate limit state for the standard design load. In the second phase, the static analysis of the structure for the effects of accidental actions from low and high seismicity was performed and it was assessed whether the main load-bearing elements of the structure would continue to comply. Given that the structure did not satisfy the accidental actions of seismic loading, various ways of structure strengthening were designed and analyzed for their impact on the global and local behaviour of the structure. Also the designing of additional steps for structural reliability were performed. Static analyzes were performed in Scia Engineering and RFEM Dlubal software.

Abstract:

This work aims to the design of a carbon fiber bicycle frame with production technology suitable for piece production. The work summarizes the methods of production of composite frames and important parameters that must be respected when designing the frame. A Gravel frame was chosen for the design. The frame was designed for production using stainless steel printed lugs with glued composite tubes. The proposed solution was strength tested. The work also contains a design of a production jig for the construction of bicycle frames.

Abstract:

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.

Abstract:

This master thesis deals with the strain, stress and reliability analysis of the safety frame of racing car. The safety frame is a part of passive safety, which it becomes active in a case of impact. The safety frame makes a reinforcement of the car body and provides its sufficient stiffness. The first part of the master thesis is focused on determination of stress and strain states during the static loading tests and their analysis. The loading conditions are prescribed by homologation regulations of Fédération Internationale de l´Automobile (FIA). The problem is solved, making use of computational modeling utilizing the Finite Element Method (FEM). The first part of thesis is used for the stiffness and safety analysis under the static loading test. The second part deals with the effect of loading velocity on the stress and strain states using the computational modeling and solver LS-DYNA.
