Sažetak
Amortizeri su osnovni element sistema za oslanjanje vozila. Sistem za oslanjanje treba da obezbedi upravljanje vozilom i udobnost putnika. Kontakt točka i puta treba da bude što bolji, jer se time obezbeđuje lako upravljanje i dobre kočne performanse vozila. Pri tome, svaki točak, ponaosob, mora imati dobar kontakt sa podlogom. U cilju poboljšanja udobnosti, uticaj pobude puta se mora minimalno prenositi na putnike. Tokom projektovanja vozila, velika pažnja se posvećuje optimalnom izboru parametara sistema za oslanjanje (koncepcija, krutost opruge, prigušenje amortizera). U ovom radu su prikazani rezultati eksperimentalnih istraživanja sprovedenih na amortizerima zadnjeg sistema za oslanjanje jednog vozila koje se nalazi trenutno na tržištu. Eksperimentalna ispitivanja su izvedena u uslovima pobuđivanja ponavljajućim udarnih opterećenja.. Na osnovu dijagrama koji povezuju sile sa kinematskim parametrima (pomeranje, brzina, ubrzanje), uz korišćenje metode 'crne kutije' identifikovan je matematički model amortizera.
