DLG Pow erMix Test Overview

IPG / Apply & Innovate 2016 | 21/ 09/ 2016

DLG:

  • Deutsche Landwirtschafts-Gesellschaft (German Agricultural Society)
  • I ndependent organization with focus on agricultural and food testing

Basis of Test:

  • 13 cycles representing work performed by a tractor
  • Tractor is loaded dynamically by drawbar, PTO and hydraulics
  • Allows comparison of fuel consumption between different tractors

Cycle Developm ent:

  • Field measurements carried out by DLG
  • Supplemented with field data from manufacturers and different

universities.

  • Today’s Tractor Developm ent Program s:

Clear focus on fuel economy (Market) Significant changes in powertrain area (Emissions)

  • DLG Pow erMix

is a representative test method but … … requires fully functional prototype at DLG

Gap: Design already frozen, changes are difficult to im plem ent! Solution: Pow erMix Replication Predict DLG PowerMix results early in developm ent program (or even concept selection) with high level of repeatability (identify small differences)

Motivation for DLG Pow erMix Replication

Sum m ary & Conclusion

24

  • Vehicle in the Loop test methodology provides powerful tool to

replicate DLG PowerMix

  • The test results are showing good correlation between DLG

PowerMix and Mannheim LabPowerMix Test

  • Several influencing factors (ambient temp, steering,

wheel/ road interaction) eliminated or reduced

  • High level of automation improve repeatability
  • Applicable at an early prototype stage or even concept

selection
