20.500.12556/RUL-95903 Numerična in eksperimentalna modalna analiza rotacijskega enkoderja Numerical and experimental modal analysis of a rotary encoder Magistrsko delo predstavlja numerično in eksperimentalno modalno analizo rotacijskega enkoderja, ki ga proizvaja podjetje RLS Merilna Tehnika, d. o. o. Enkoder sestoji iz zaznavalne glave, ki bere signal, in obroča s feromagnetno gumo, ki signal oddaja. Signali so zaznavani s Hallovim zaznavalom, zato je razdalja med modulom in obročem ključna za njegovo pravilno delovanje. Če se ta preveč poveča, enkoder ne more več opravljati svoje naloge. Numerični model je bil postavljen v programu Comsol. Meritve so bile opravljene v prostorih in z opremo laboratorija LADISK. Ugotovili smo, da numerični model dobro popisuje realno nihanje enkoderja. This thesis contains a numerical and experimental modal analysis of a rotary encoder produced by the company RLS Merilna Tehnika d.o.o. Encoder consists of a reading head, which detects the signal, and a ring with the feromagnetic rubber, which emitts the signal. Encoder uses Hall sensors for operating, hence the distance between module and ring is a crucial parameter. If this distance is too great, loss of signal occurs and consequently encoder cannot read the signals. Numerical model was established in Comsol software. Measurements were conducted in chambers and with equipment of the laboratory LADISK. It was established, that numerical model represents behaviour of a real encoder very good. tiskano vezje obroč s feromagnetno gumo končni elementi vibracije modalni parametri Python Comsol Printed circuit board ring with feromagnetic rubber final elements vibrations modal parameters Python Comsol true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2017-09-23 07:15:00 2017-09-23 07:15:05 2023-10-27 12:50:10 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 201656 1210.pdf 1210.pdf 1 68822682535037BCD8C94F0ACB5AE334 dddb34972122506899b5893fa42fe03ab7f97acad921cc0ebecfd712a22d496e dacbd8ee-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/ffe6e485-f91a-44e6-91b8-918b92ecd11f https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=104551 Fakulteta za strojništvo 0 0 0
