Effects of vibration and impulses during transportation of goods

Transport blaga od proizvajalcev do uporabnikov postaja čedalje bolj raznolik, zato so artikli med potjo izpostavljeni veliko različnim vplivom med katerimi so za poškodbe pošiljk največkrat krive mehanske obremenitve. Da bi se poškodbam v čim večji meri izognili, je pomembno, da razumemo od kod mehanske obremenitve, kot so vibracije in sunki sil, kako jih izmeriti in obvladovati. V sklopu zaključne naloge je bila s pomočjo mikrokrmilnika Arduino izdelana naprava, ki se lahko uporablja za nadzor sunkov sil, ki so jim podvržene pošiljke tekom transporta. Senzor vibracij, ki smo ga pri tem uporabili, smo umerili s pomočjo pospeškomera in improviziranega preizkuševališča.Transportation of goods from producers to customers is becoming more and more diverse, therefore the articles are exposed to many different influences and are often damaged during transportation. Damages that occur are most commonly induced due to mechanical stresses like vibrations and impulses. In order to avoid it as much as possible, we have to understand from where the loads originate and how to measure and control them. In the scope of presented diploma thesis we developed a measuring device using Arduino microcontroler. It can be used to monitor the occurrence of impacts during transportation. The monitoring device was calibrated using piezoelectric accelerometer on the improvised test rig
