Optimalizace výrobního procesu ve vybraném podniku / Optimization of manufacturing process in a selected company

Kubíček, František January 2020 (has links)
This thesis is primary focused on optimization of the production process in a selected company.Teoretical part of this thesis is the result of literature research of Lean Six Sigma, which is mostly used by the company. It is a brief insight to an issue and introduction of the most often used tools from Lean Six Sigma methodology, which were used afterwards in practical part of this thesis. Also there is an introduction of the company and its production portfolio. Crucial part of this thesis is it‘s practical part focused on improving of current situation on the production line with an economical and technical assessment. The main goal was to create more compact and smaller area of product line with lower work in progress.

Šestiválcový řadový vznětový motor s vypínáním válců / Six-cylinder in-line diesel engine with cylinder deactivation

Novosád, Ivan January 2020 (has links)
Master 's thesis deals with design of a drivetrain of six cylinder inline engine with cylinder deactivation for heavy agricultural vehicles. In this thesis were devised various possibilities of crankshaft balancing, the best design solution of counterweight was based on optimization in software Catia. Further, the crankshaft was analysed for force and momentum loading and torsional vibration, based on which, the torsional vibration damper was designed. There were considered several options for cylinder deactivation, which were analysed for finest run of engine and the best thermal distribution. Based on these criteria, the best option was to deactivate 2nd and 5th cylinder. The crankshaft was analysed for the fatigue failure by finite element method. The fatigue failure is the most dangerous case for the crankshaft, the resulting safety factor for this limit state is 3,05.
