| Abstract | Razvojem tehnologija i materijala tehnička rješenja koja su prije bila nepraktična ubrzano
dobivaju na značaju, te oblikuju metode ratovanja, kako na strateškoj, tako i na operativnoj i
taktičkoj razini. Jedno od takvih rješenja je hibridni, tj. električni pogon vozila čija integracija
rezultira povećanjem dometa pri vožnji s učestalim promjenama brzine, koja je karakteristična
za neuređeni teren, te može omogućiti tihi rad vozila, što uvelike pospješuje taktičke
sposobnosti vojnih jedinica, a i civilnih službi. Najveću korist od takvog sustava imat će
specijalne postrojbe čija djelovanja često zahtijevaju neprimijećenost. Trenutno na širem tržištu
ne postoje hibridne izvedbe lakih i visokomodularnih vozila kakva bi bila primjerena za vojnu
namjenu, tako da se umjesto čitavog razvoja koncipira prerada dostupnih komercijalnih vozila.
Postavljaju se zahtjevi na prerađeno vozilo, te se provodi analiza tržišta terenskih vozila i
odabire najpogodniji kandidat. Provodi se evaluacija različitih izvedbi hibridnog sustava
temeljem performansi, cijene i prostornih ograničenja na temelju izrađenog 3D modela.
Proveden je orijentacijski proračun otpora vožnje i uspoređen s karakteristikama predloženog
elektromotora, te su predloženi dopunski sustavi s ciljem unaprjeđenja sposobnosti vozila u
korist specijalnih vojnih postrojbi i civilnih službi. |
| Abstract (english) | With the advancement of materials and technology, previously unfeasible technical solutions
are rapidly gaining prominence, shaping the methods of warfare at the strategic, as well as the
operational and tactical levels. Among these solutions stand hybrid vehicle propulsion systems,
with the ability of pure electric drive, the integration of which results in an extended range while
driving with frequent changes in speed, which is characteristic for off-road driving, and enables
silent drive capability, which greatly improves tactical capabilities of military units and civil
services. Special forces, whose missions frequently necessitate cover operations, are anticipated
to derive the greatest utility from such a system. Currently, there are no hybrid versions of ultra
light and highly modular vehicles suitable for military use on the wider market, so instead of
the entire development, a concept of modification of available commercial vehicles is produced.
Requirements are set for a retrofitted vehicle, off-road vehicle market analysis is carried out
and a suitable candidate is selected. Different hybrid systems are assessed by criteria of
performance, price and spatial constraints based on the created 3D vehicle model. Approximate
calculations of required battery capacity, mass and required volume, as well as driving
resistances, which are then compared with the characteristics of the proposed electric motor.
Furthermore, some supplementary systems are proposed, with the aim of enhancing the
vehicles capabilities for the benefit of special military units and civil services alike. |
