Abstract
Práce se zabývá vývojem projektu SK253 (rolety panoramatické střechy vozu) od úplného začátku až po současný stav. Během celého období bylo třeba vyřešit několik klíčových otázek v souvislosti s dodržením minimální a maximální síly pro manipulaci s roletou. Specifikace sil je stanovena zákazníkem. V rámci předsériové fáze (APQP) bylo třeba stanovit polohu síly v tolerančním intervalu. Dále byla ověřena normalita naměřených dat a poté vypočteny indexy způsobilosti procesu a výkonu. S blížícím se vstupem do sériové výroby se vyskytl problém se samovolným zatahováním rolet při jízdě. Závěr práce je proto věnován dynamice rolety a možnostem řešení tohoto problému.
The thesis deals with the development of the project SK253 (blinds for car sunroofs) from the very beginning until today. During the entire period was necessary to solve some key issues related to compliance with the minimum and maximum force which is needed for manipulation with blinds. Force specification is determined by the customer. During the pre-production phase (APQP) was necessary to define the force position within the tolerance interval. Afterwards the data normality was verified and then the process and performance capability indexes were calculated. With the impending entry into the serial production occured a problem with spontaneous closing of the blinds during the ride. The conclusion of the thesis is devoted to the dynamics of blinds and possibilities of solving this problem.
