Design of strain gauge devices for safety belts load measuring
Lontras, Martin ; Jebáček, Ivo (referee) ; Mališ, Michal (advisor)
The aim of this thesis is to design, produce and experimentally verified measuring device for measuring force in seatbelt, by using strain gages. First are discussed possibilities of measuring force by using device placed in between two parts of seat belt or in anchor point. These suggestions were not accepted for various reasons. Therefore is further described girder, which belt slightly deflected so that part of the load is transferred to the strain gauge measuring element. As default concept is choosen aluminum U-profile, in which is placed measuring mechanism. There are performed calculations of basic geometry and stress control. Then is described manufacturing and calibration on universal testing machine. In conclusion is realized measuring of the force in seat belt, which is loaded by shock force, occasioned by dropping weights from a certain height, which simulates the behavior of the belt and gauge during a crash test.

Analysis of Driving a Passenger Vehicle with a Trailer
Šujan, Tomáš ; Kropáč, František (referee) ; Vémola, Aleš (advisor)
The subject of this thesis is the analysis of the negative effects associated with the operation of a trailer for a personal vehicle with respect to the design speed, technical checks and analysis related legislation. Its work is drawn from the measurement, cooperation with leading Czech production plant trailers Vezeko s.r.o., an organization engaged in the implementation of engineering controls DEKRA Automobil a.s. and available literature, including electronic resources. Results of the work end with proposals for specific measures to minimize the identified adverse effects.
