Vehicle suspension design and testing methods
Šenkeříková, Veronika ; Tobiáš, Martin (referee) ; Fojtášek, Jan (advisor)
This bachelor's thesis is dedicated to suspension systems and their typology. Furthermore, the basic geometric parameters of these systems are discussed in the thesis. Types of suspensions (axles) are classified according to the interdependence of individual wheels. Subsequently, the thesis provides an overview of simulation software for chassis development and testing in the virtual phase of development. These are divided according to computational principles, result evaluation, and environment. The last section addresses issues related to chassis testing and its properties as a whole, testing individual chassis components to verify durability etc. The thesis includes specific representatives of testing conditions. For each chassis component, a representative from each chassis subsystem is selected. This thesis provides a current overview of methods and tools used in the automotive industry for development and testing. It demonstrates the importance of both virtual testing and testing on testbeds for already finished products.

Development and weight reduction of central housing for commercial vehicles
Blecha, Martin ; Pittl, Michal (referee) ; Píštěk, Václav (advisor)
The theoretical part of the thesis is focused on the clarification of the central housing function and its placement in a truck. The central housing function and placement depend on a vehicle chassis design. There is the weight optimization of the housing which is solved in the practical part of the thesis. The optimization is based on strength calculations of the Finite Element Method. There are weight savings and financial savings evaluated at the end of the thesis.

Retractible landing gear design for Z 143 LSi airplane
Gregor, Jiří ; Vaněk, František (referee) ; Píštěk, Antonín (advisor)
The diploma thesis deals with the design of the replacement the Z 143 LSi landing gear with the new VUT 100 type landing gear in a retractable system. The first part of this thesis is devoted to the description of the Z 143 LSi aircraft and its landing gear and the description of the retractable landing gear type VUT 100. The next part describes the possible variants of the installation the VUT 100 landing gear, which are critically evaluated. Then there is selected the final variant for the installation, which is designed in Catia V5 software. The final design includes remotorization with Lycoming IO-390 and new design of engine bed. For the proposed solution, a new mass analysis with the calculation of centrations, new cases of ground load, a new flight envelope of load and additional cases of load of a new engine bed are prepared. The proposed engine bed is analyzed by the finite element calculation method in the MS Patran software. Finally, a possible scheme of the chassis retraction system is proposed.

Testing of Vehicle Suspension Components
Šidla, František ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This bachelor thesis deals with issues related to testing car chassis components during development. Automobile transport is the most common type of long-distance transport. That's why vehicles are constantly evolving to provide the best possible performance. Increasing demands on consumers are being placed on vehicles because of the introduction of modern technologies. New technologies and concepts need to be thoroughly tested that they can be properly integrated into existing models. Test devices for determining the characteristics of the chassis are generally described here using specific examples of individual machines. Subsequently, the work clarifies the testing of the service life of individual parts of the chassis. The last part is devoted to the conceptual design of a simplified hydraulic device for testing coil springs. From the calculated characteristics, a hydraulic actuator and pump are selected from the relevant catalogues. In conclusion, the importance of car testing in development is summarized, individual types of testing are described and the readiness of test devices for the future is indicated.

Urban three-wheeled vehicle with electric drive
Černík, Adam ; Porteš, Petr (referee) ; Tobiáš, Martin (advisor)
This bachelor thesis deals with the conceptual design of the chassis of a three-wheeled. The total payload od the vehicle is 160 kg. At the beginning, the work deals with the search for different types of chassis in used three-wheeled vehicles. The advantages and disadvantages of various chassis concepts and the subsequent choice of one them are also summarized. Then the conceptual parameters of the vehicle are selected. At the end a 3D model is modelled in program Inventor, which corresponds to the selected conceptual parameters. This model is used to visualize the designed chassis of three-wheeled vehicle.
