20.500.12556/RUL-103274 Analiza kinematike na napravi za kompaktiranje žarilnih svečk Kinematic analysis on compacting machine for glow plugs V proizvodnem procesu svečke za hladen zakon dizelskih motorjev se izvaja proces kompaktiranja magnezijevega oksida (MgO) z vibriranjem. Cilj naloge je kontrola tega procesa z namenom zagotavljanja kvalitete. Z optimiziranim procesom se namreč doseže višjo gostoto nasutja, ki pozitivno vpliva na življenjsko dobo samega izdelka. Potreba po kontroli vodi v analizo kinematike procesa. S tem namenom se je na napravi za kompaktiranje zajemalo pospeške med procesom kompaktiranja. Podatke se je nato pretvorilo v frekvenčno domeno in se jih primerjalo s teoretičnim harmonskim nihanjem, ki naj bi se tudi zagotavljalo med procesom. Rezultati kažejo, da dejansko stanje ne kaže na harmonični odziv, kar otežuje proces kontrole in optimizacije. In the production process of heating (glow) plug for diesel engines is a process of compacting magnesium oxide (MgO) with vibrations. The purpose of the assignment is controlling the process for the insurance of quality. With optimised process, we can insure higher density of MgO, which has a positive influence on life expectancy of the plug. The need for control leads to analysis of kinematic of the process. For this reason, we gathered accelerations during the process of compacting. We than transformed the data to frequency domain. We then compared this data to theoretical harmonic oscillation that is supposed to be provided during the process. Results show that real data does not seem to be harmonic, which will make the process of control and optimisation harder. kompaktiranje Fourierova transformacija pospešek frekvenca pospeškomer nihanje compacting Fourier transformation acceleration frequency accelerometer oscillation true false false [T.
