20.500.12556/RUL-95503 Naprava za karakterizacijo linearnega koračnega aktuatorja Device for Characterization Linear Stepper Actuator Delo obsega razvoj in izdelavo testne naprave za merjenje dinamičnega odziva linearnega koračnega aktuatorja ter test aktuatorja. Za potrebe meritev in računskega modela preučimo delovanje linearnega koračnega aktuatorja (LSA). Aktuator mora dosegati zahteve in specifikacije, ki jih pomerimo s pomočjo testne naprave in primerjamo z računskim modelom. Testna naprava aplicira konstantno aksialno silo (32 N) na premikajoči del aktuatorja in omogoča merjenje aksialne sile in pomika sočasno v časovni domeni. S pomočjo vgrajene merilne opreme merimo sile v območju med 0 in 200 N ter pomik med 0 in 25 mm. Konstantno aksialno silo lahko spreminjamo z dodajanjem 100 gramskih uteži. S pomočjo testne naprave izvedemo meritve ter jih primerjamo s simulacijo. Odstopanja med meritvijo in simulacijo vrednotimo. Pri gibanju aktuatorja se pojavi nihanje sile, ki ga okarakteriziramo glede na mehanizme nastanka. Na koncu je podana ocena o ustreznosti aktuatorja in testne naprave glede na zahteve in specifikacije. The thesis describes development and manufacturing of a test device for measuring dynamical response of a linear stepper actuator (LSA) and testing of the actuator. Operation of the actuator is examined to facilitate design of experiments and develop a computational model. The actuator must meet the requirements and specifications, which we measure with the developed test device and compare the results with predictions of the computational model. Test device applies constant axial force (32 N) on the moving part of the actuator and enables synchronous measurement of axial force and displacement in time domain. With the installed measuring equipment we measure forces in the range between 0 and 200 N and displacements in the range between 0 and 25 mm. The constant axial force is adjustable with 100 g weights. We analyze discrepancies between measurement and simulation. Axial movement of the actuator causes oscillation of the axial force, which we characterize and analyze its origin. Finally, an assessment is given of adequacy of the actuator and test device with respect to the requirements and specifications.
