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.

Motors for automotive wipers
Sekerka, Jan ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
This thesis deals with the innovation of DC motors with permanent magnets used in automotive technology to drive wiper mechanism to reduce the volume and weight of the active materials. Potential innovations is mainly using magnets of the magnetic rare earths, such as Neodym or samarium-cobalt. Another option is to reduce the rotor to decreases the number of threads (here, it's all about, what are the requirements for performance). The result is an innovative motor, wherein the volume of the permanent magnets is reduced by 65% and total volume of the motor by 23% while maintaining the rotor parts. Also slightly raised performance with Neodymium permanent magnets.

Rankin cycle for waste heat recovery of internal combustion engines
Kučinský, Josef ; Fiedler, Jan (referee) ; Brázdil, Marian (advisor)
This bachelor thesis deals with Rankine cycle as a method of waste heat recovery for internal combustion engine. Firstly, internal combustion engine and some technologies on waste heat recovery are described simply. Secondly, Rankine cycle and its utilization in automobiles are overviewed. At the end, there are summarized results from simulations and experiments regarding the issue. It was stated in a conclusion that in case of waste heat recovery in automobile, Rankine cycle is a promising technology but it is not ready for wide application yet.
