Double drum synchronized control of hydraulic vibratory roller ARP95
Novák, Martin ; Rada, Zdeněk (referee) ; Klas, Roman (advisor)
This thesis presents solution of synchronized two smooth drum steering of tandem vibratory roller ARP 95. During the development of this machine was found insufficient synchronization of two drums. The above-described problem was solved by modifying the steering block. The correct evaluation of data measurement and understanding of the machine behaviour led to elimination of the problem. The main result of this thesis is elimination of unsynchronized behavior of two drums. Thanks to this was achieved maximum deviation between two drums 0,2°. Synchronized steering is very important for modifying the surface of the asphalt roads around the sidewalks and currently the machine ARP 95 produced by AMMANN is the top of the market when it comes to the synchronized steering.
Tilting head for mini excavators
Zámečník, Stanislav ; Sojka, Michal (referee) ; Škopán, Miroslav (advisor)
The diploma thesis deals with the structural design of the tilting hitch intended for mini-excavators. This thesis includes a critical research of similar devices. Based on this research, there is a custom design of tilting hitch with tilting using linear hydraulic motors created. Furthermore, all necessary calculations of the main parts and strength analysis of the supporting structure are carried out and drawing documentation is created. This diploma thesis was developed in cooperation with the company STAVES s.r.o..
