20.500.12556/RUL-140061 Replikacija pospeškov na potnike v avtomobilu med vožnjo z uporabo koračnega motorja Replication of acceleration loads on passengers during car commute using stepper motor V zaključni nalogi je predstavljen postopek repliciranja pospeškov, ki se pojavljajo na potnike med vožnjo. Metodologija zajema meritev pospeškov s pospeškomerom mobilnega telefona, nato pa pretvorba pospeškov z numerično integracijo in visoko-prepustnim filtrom v želeno bitno resolucijo pomikov. Z dobljeno končno datoteko pomikov smo preko programske kode napisane v programskem okolju Arduino kontrolirali bipolarni hibridni koračni motor. Na koračni motor smo namestili jermenico, preko katere je bil speljan jermen. Z laserskim vibrometrom smo nato izmerili pomike jermena v odvisnosti od časa in jih primerjali s predhodno pridobljeno bitno resolucijo pomikov. The final thesis presents process of replicating the accelerations that occur to passengers while driving. The methodology included measurement of acceleration with mobile phone accelerometer, then the transformation of acceleration measurements with numerical integration and high-pass filter in the desired bit resolution of positions. The resulting file that we installed in the program code in the Arduino IDE, we controlled a bipolar hybrid stepper motor. On the stepper motor, we attached the pulley through which the belt was laid to. With a laser vibrometer, we measured the displacements of the belt in the time domain and compared them with the previous bit resolution of positions. dinamika vožnje pospeškomeri numerična integracija procesiranje signalov koračni motorji mikrokrmilniki Arduino driving dynamics accelerometers numerical integration signal processing stepper motors microcontrollers Arduino true false false [P.
