The stress analysis and design optimizing of the trailer MEGA 25
Halama, Tadeáš ; Molva, Martin (referee) ; Kašpárek, Jaroslav (advisor)
This Diploma Thesis is dedicated to stress analysis of carrier swap bodies Mega 25 with maximum technical weight 27 000 kg and has been worked out in corporation with ZDT Nové Veselí company. The aim of this work is to stress analysis of trailer in various burdensome conditions. The first section of the Thesis is occupied with original design and burdensome condition. Then, according to these states gained strength to control the finite element method, implement and then modify the design including design of new drawbar and then create selected construction drawings prepared.

Comparison of the intercompany transport using tractors and Tatra tractors in agricultural primary production.
NEKULA, Lubomír
This bachelor thesis deals with the comparison of the intercompany transport using Tatra traktor, and the tractor transport system. The practical part deals with the measurement and observation during the transport of material in the company Rolnická společnost Lesonice a. s. The measured values of individual sets were processed and compared with each other. For comparison of the tractor transport, the most common transport system of the Czech producer ZDT Nové Veselí Mega 20 and Mega 25 was chosen. The following sets were compared: - 2 sets of Tatra tractor T158 with the trailer Trail King - Challenger 545B sets with the trailer Mega 25 - New Holland TM 155 sets with the trailer Mega 20
