Trailer for the building machinery
Kramoliš, Robert ; Kubín, Martin (referee) ; Pokorný, Přemysl (advisor)
In this diploma thesis, I deal with conception and strength analysis of lowbed detachable gooseneck trailer for construction machinery. First part of thesis is about trailers used these days with brief legal requirements for this device. Rest of the thesis contains construction of trailer, creation of finite element model, and presentation of achieved results. This diploma thesis contains drawing documentation.
Analysis of the trailers safety features
Pavliš, František ; Kubín, Martin (referee) ; Kašpárek, Jaroslav (advisor)
This diploma thesis deal with safety components of trailer and semitrailer technology, especially the elements for underrun protection. The first part deals with the legislative requirements on which safety elements are based. In another part are mentioned the construction solutions of underrun protection devices from the portfolio of company SVAN Chrudim s.r.o. Finally, the computational part is processed to verify sufficient strength of underpass protections.
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.
Traveling Crab 360 t
Sláma, Ondřej ; Kubín, Martin (referee) ; Pokorný, Přemysl (advisor)
The topic of this diploma thesis is the frame of the foundry crane with load capacity 360 t. The frame is analysed by strength inspection and fatigue strength inspection according to norm ČSN EN 13001. The analysis are made by using finite element method on shell model. The diploma thesis was made in cooperation with Královopolská a.s. company.
Conceptual design of bridge crane 8 tonne
Franc, Šimon ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
This bachelor thesis deals with conceptual scheme of a bridge crane with carrying capacity of 8 tons. Intention of this thesis is to scheme out the main specifications and size of this bridge crane. First of all we design and calculate the main bridge girder. Afterwards we calculate and design the cross bars and the travelling wheels. At last the desigh of an electromotor for powering the movement of the bridge crane takes its place.
Analysis of carriage of Top Drive of drilling tower
Kříž, Jakub ; Kubín, Martin (referee) ; Pokorný, Přemysl (advisor)
The subject of this diploma thesis is determination of the cause of crack formation at the carriage Top drive for MND Drilling & Services company. The aim of the diploma thesis is to analyze the load states of the component. Furthermore, the aim is to create a computational model and boundary conditions and to create suggestions of improvements leading to the elimination of cracks. And finally, to evaluate the results of construction improvements..
The Development of the New Concept of Autonomous Cranes
Kubín, Martin ; Knoflíček, Radek (referee) ; Hrabovský, Leopold (referee) ; Škopán, Miroslav (advisor)
The presented PhD thesis aims to verify the possibilities of using capacitive accelerate sensors on the crane and handling technology. Capacitive acceleration sensors of MEMS type are currently widely used in electronics, e.g. laptops and mobile phones. Using these sensors could help to automate cranes, which would eventually reduce the financial costs of material handling. Precise knowledge of their own condition and position of the machine and the load is a necessary part of autonomous manipulators. The first part of thesis deals with the exploration of scientific research in the Czech Republic and abroad. Furthermore the options of mathematical description of moving the load on the rope tow are described including solved examples. One chapter is devoted to the description of sensors that could be used in the automation of cranes. The main part is focused on description of several experiments. The experiments were conducted in a lab constructed specially for this measurement. Mainly basic simpler models are described illustrating abilities of the sensor. The last part outlines further possible progress of research in this area.
Control stress analysis of LVS 511 gear
Macka, Jan ; Kubín, Martin (referee) ; Pokorný, Přemysl (advisor)
This master’s thesis deals with analysis of the gearbox housing of forwarder LVS 511. Theme is designed by Strojírna Novotný s.r.o. Objective of the work is to perform strain stress analysis of gear housing and main transmission shaft. The main part of the thesis is focused on creating of finite element model and evaluation in NX I-Deas software.
Slot adjusting mechanism of cone crusher
Huňka, Jan ; Kubín, Martin (referee) ; Pokorný, Přemysl (advisor)
This master’s thesis deals with the obtuse-angled cone crushers especially about design of the individual parts of the adjustment mechanism. Most space is devoted to functional calculation and subsequent technical construction of the new design of obtuse-angled crusher where the output setting is adjusted using the motion thread and hydraulic locking system for compensating the thread clearance. The parameters are chosen with regard to the already established older types of cone crushers produced by PSP Engineering, a.s. An inseparable part is the calculation verifying the functionality of the motion thread and gearing. Another essential part of this work are stress analysis of the slot adjusting mechanism design using finite element method and considering two states - adjusting of the slot and crushing itself.
