Abstract
As a stage in the development of the next generation of wheel loaders, all systems are evaluated in order to minimize the energy consumption. This master thesis aims to investigate the energy consumption for four linkages with different design. It will also investigate how the energy
consumption changes when an electro-hydraulic compensation is added in order to keep the load parallel and what the total cost of ownership is. Work cycles for how the linkages should move during simulations were developed, both for the use of forks and for the use of a bucket. Models have been built using the software’s AMESim, MatLab and SimuLink. The results from the simulations were analyzed and the energy consumption for the four different linkages was... (More)

This results combined with manufacturing cost of the linkages resulted in a total cost of ownership (TCO) for the different linkages, based on the factors; work hours during the linkage´s lifetime and at what share it is driven with forks contra bucket. The result clearly showed that one of the linkages was favorable to use in a TCO perspective and that linkage was also recommended to use on future wheel loaders. (Less)

Som ett steg i utvecklingen av nästa generations hjullastare görs studier av olika delsystem för att se var energiförbrukningen ligger. Denna masteruppsats har som mål att ta reda på energiförbrukningen för fyra länkage med olika konstruktion. Den kommer även att undersöka hur energiförbrukningen förändras när en elektro-hydraulisk kompensering introduceras för att hålla lasten parallell samt vad totalkostnaden för de olika länkagen blir. Arbetscykler har tagits fram för hur länkagen ska röra sig under simuleringar, både för gaffelhantering och skophantering. Modeller har byggts med AMESim, MatLab och SimuLink. Resultaten från simuleringarna har analyserats och energiförbrukningen för de fyra olika länkagen fastställdes. Dessa resultat... (More)

Arbetscykler har tagits fram för hur länkagen ska röra sig under simuleringar, både för gaffelhantering och skophantering. Modeller har byggts med AMESim, MatLab och SimuLink. Resultaten från simuleringarna har analyserats och energiförbrukningen för de fyra olika länkagen fastställdes. Dessa resultat tillsammans med tillverkningskostnaden för länkagen ligger till grund för totalkostnadsanalysen som är en funktion av antal arbetstimmar och andel av tiden som länkaget används med gafflar kontra skopa. Resultatet visade tydligt att ett av länkagen hade en lägre totalkostnad. Rekommendation av vilket länkage som bör användas på framtida hjullastare baseras på totalkostnadsanalysen och därför rekommenderas det länkage som hade lägst totalkostnad. (Less)
