Computer simulation model concept of an automated sorting system
Dvořák, Patrik ; Kašpárek, Jaroslav (referee) ; Urbánek, Michal (advisor)
In response to the growing demand for fast sorting of items, this bachelor thesis focuses on automated sorting systems. It describes the whole system in detail, from the basic principle, to the partitioning, the technologies and sensors used, to the advantages and diverse applications. It includes current trends for small volume shipments in this area. The thesis presents the concept and layout used to create the simulation model in Tecnomatix Plant Simulation software from Siemens. A matrix of experiments was created for the simulation model. Subsequently, simulation experiments were performed to find an optimization solution. Finally, verification and validation was performed where the simulation model was compared with the analytical calculation result.
Common-rail System for Large Engines
Dvorák, Patrik ; Řehák, Kamil (referee) ; Dundálek, Radim (advisor)
This bachelor’s thesis is devoted to specifications of common-rail injection systems for large engines used in heavy industry. Basic components of the common-rail system such as injectors, high pressure fuel pumps their function and their division into individual categories are discussed. Next, specific problems that must be faced by power plants if this power category is discussed, such as high injection pressures and fuel filtration. This thesis also includes examples of solutions for specific injection systems for large engines from renowned manufacturers. The topic of the production of harmful substances in the exhaust gases is also briefly discussed.
