Analysis of Required Characteristics of an Agricultural Transporter Prime Mover

Abstract

Depending on transport conditions, light agricultural transport vehicle can represent more favorable alternative to conventional approach to agricultural transport, i.e. use of tractor with trailer or a lorry. This way it is possible to achieve greater energy efficiency, better soil protection, more efficient transport etc. In this paper development of agricultural transport vehicle is analysed from the point of view of required characteristics of the prime mover. Powertrain performance characteristics needed in terms of vehicle tractive characteristics are considered, taking into account other relevant parameters as well. Maximum engine power should be close to interval of 25-35 kW. Final choice of engine that will be used has to be made based on technical and economic analysis of existing designs available on the market.

U zavisnosti od uslova transporta, upotreba lakog poljoprivrednog transportnog vozila može predstavljati povoljniju alternativu upotrebi konvencionalnih načina transporta u poljoprivredi, odnosno traktora sa prikolicom ili teretnog vozila. Ovim putem moguće je postići doprinos povećanju energetske efikasnosti, poboljšanju zaštite zemljišta, efikasnijem obavljanju transportnih operacija i sl. U ovom radu analizira se razvoj poljoprivrednog transportera pre svega sa stanovišta potrebnih karakteristika pogonskog motora. Razmatrane su potrebne performanse sa aspekta vučno-brzinskih pokazatelja, ali i drugih relevantnih parametara. Potrebna snaga pogonskog motora treba da bude bliska intervalu od 25-35 kW. Konačan izbor motora koji će biti korišćen treba izvršiti na osnovu tehničko-ekonomske analize izvedenih rešenja raspoloživih na tržištu.
