Mechanical analysis of the subsystem of the tower crane
Urbánek, Roman ; Venský, Jiří (referee) ; Fuis, Vladimír (advisor)
The bachelor thesis deals with the solution of a subsystem of a tower crane with a passive effect (NNTP). First part describes tower cranes and their parts. The following part is a description of the theoretical and physical laws of statics and dynamics. In the practical part, various states of motion of a specific modeled subsystem are calculated, which shows a trolley of the tower crane. The aim of the calculation of each configuration is to determine the numerical values of the contact forces in the links, to analyze the dynamic quantities and to evaluate the functionality of the links. Numerical values of unknown parameters were calculated by solving a system of linear equations in the calculation software Matlab.

Technological manipulator of smoking-chamber
Gajdušek, Jakub ; Zajíc, Vlastimil (referee) ; Pokorný, Přemysl (advisor)
This work designs overall structural design of technological manipulator of smoking- chamber, which serves to move the trolleys with food between smoking and chilling chamber. Chambers are connected in a single device. Trolleys are considered with full and uniformly distributed load. Work includes a 3D model of equipment and production documentation.

Trolley for manipulation
Jílek, Josef ; Nevrlý, Josef (referee) ; Brandejs, Jan (advisor)
This Bachelor thesis deals with solution of interoperative material transport and design of trolley for manipulation of flooring rolls. The trolley was designed with the aim to increase safety and simplify the manipulation. It is simple welded frame made of metallurgical products. The trolley was designed to transport rolls with weight about 150 kg. Factor of safety was 23,5. It means that the construction of frame is well-dimensioned. This thesis also includes complete drawing documentation

Analysis of Deceleration of Trolleybuses and Evaluation of its Impact on Standing Passengers
Semmler, Petr ; Škrabal, Jaroslav (referee) ; Vémola, Aleš (advisor)
This thesis is focused on analysis and evaluation of the trolley deceleration effect on his standing passengers. The first part focuses on theoretical knowledge in terms of legislative requirements for the operation of trolleybuses and transport standing passengers. This section also lists physical findings during deceleration and forces acting on the vehicle. The central part is divided into two measurements. The first measure is aimed at obtaining data (deceleration) and information (number of passengers, increased stability, and fall) of the normal operation of the standing passengers in interior trolley. The second measurement will be focused on driving performance demonstration tests with the interior trolley helpers in various traffic situations. The conclusion of this thesis will summarize the values and knowledge of both measurements. The evaluated data set will limit the slowdown in the trolley passengers where standing still maintains stability.

Soustava těles s pasivním účinkem s brzdou
Genco, Ondřej ; Hájek, Petr (referee) ; Fuis, Vladimír (advisor)
This thesis deals with the solution of the body system using NNTP static theory model. The introductory part defines the basic magnitudes and concepts, describes the constraints and the types of passive effects. In the practical part, the influence of passive effects on different moving states in the particular system of the towed trolley is determined. Furthermore, two variants of mechanical friction brakes are designed and compared. The numerical values of unknown parameters are determined by solving the system of linear equations in Matlab.
