Analiza obratovanja vojaškega terenskega vozila z namenom hibridizacije njegovega pogonskega sklopa

Kovačič, Luka (author), Ambrož, Miha (mentor), Zupan, Samo (co-mentor)

Magistrsko delo obravnava področje hibridizacije pogonskih sklopov vojaških terenskih vozil. V delu so predstavljene zmogljivostne zahteve zanje, podani so nekateri koncepti generičnih arhitektur hibridnih električnih pogonskih sklopov ter osnove s področja regenerativnega zaviranja. Z analizo opravljenih pospeševalnih in zavornih preizkusov vozne dinamike SKOV 8 × 8 Svarun smo ovrednotili njegove pospeševalne in zaviralne zmogljivostne lastnosti. Na podlagi kontinuiranih meritev smo določili pet karakterističnih obratovalnih voznih ciklov in izračunali oceno energijskih potreb ter oceno teoretične razpoložljive regenerativne zaviralne energije za vožnjo znotraj njih. Izvedli smo tudi meritev za določitev skupnega voznega upora vozila. Rezultate analiz obratovanja vozila smo povezali s teoretičnimi izhodišči zmogljivostnih zahtev in ocenili primernost predstavljenih posameznih hibridnih arhitektur.

• Title: Operation of a Military Off-Road Vehicle Analysis with the Purpose of Hybridization of its Drive Assembly

Abstract

Master's thesis deals with the field of hybridization of military off-road vehicle drive trains. In the thesis, we present their performance requirements, some concepts of hybrid electric drive assembly generic architectures and basics in the field of regenerative braking. Based on the analysis of the performed accelerating and braking tests of the 8 × 8 Svarun medium wheeled armoured vehicle driving dynamics, we assessed its accelerating and braking performance characteristics. Based on continuous measurements, we determined five characteristic operating driving cycles and calculated an estimation of the energy needs, as well as an estimation of the theoretically available regenerative braking energy for driving within them. We also performed measurements in order to determine the total running resistance of the vehicle. We combined results of the vehicle operation analysis with theoretical starting points of the performance requirements and estimated suitability of the presented individual hybrid architectures.
