Analysis the safety mechanism of the trailers
Pantůček, Michal ; Kubín, Martin (referee) ; Kašpárek, Jaroslav (advisor)
This diploma thesis is engaged in the analysis of a safety mechanism, which is a part of a truck trailer. This mechanism provides a safe and firm connection of a container to the trailer. Primarily abroll containers according to German standard DIN 30 722 are being transported. The introductory part of the thesis deals with the current traffic condition and the accident rate in the Czech Republic. Legislative requirements for safety elements of trailer technology for road transportation are further defined. They are followed by a recherche of industrial solutions for securing mechanisms. Consequently calculations to obtain necessary securing force were performed. An analysis of the mechanism kinematics was carried out then. A structural check of selected mechanism elements was carried out following the kinematics check. Further, an optimalization of a transom design was carried out followed by another structural check. The structural checks were carried out using both the analytical method and the finite element method. In conclusion design documentation was elaborated. This diploma thesis was elaborated in cooperation with the SVAN Chrudim s.r.o.

Design of dual-chamber pneumatic spring
Pantůček, Michal ; Roupec, Jakub (referee) ; Macháček, Ondřej (advisor)
This thesis is engaged in the design of a pneumatic spring which will be useful for a design of a strut intended for cosmic applications. The design will be supported with an analytic calculation which to be subsequently verified by means of experiments, however, those reach beyond the scope of this thesis. The spring will be a part of a strut with adjustable shock damping. For this reason it is desirable for the spring to have the lowest passive resistances occurring mainly during sealing mutually moving parts. For the spring they are the piston, the piston rod and the cylinder. On the theoretical level the thesis should explore the possibility of replacing conventional sealings by unconventional ones and possibly determine the influence upon dynamical behaviour of the spring where the piston would not be sealed at all.
