Working Simulation and Test of Electric Tractor Based on Virtual Instrument

Test-bed for electric tractor (ET) was built according to the requirements in working simulation of ET. The test system for ET was developed by virtual instrument technology based on the LabVIEW according to the requirements of multi-parameter dynamic acquiring, storing and displaying in the process of test. The simulation test of the ET plowing was carried out using this test system. The voltage and current of battery, as well as transmission efficiency were collected. The experiments show that the test system of ET is running stable and reliable, which can able to meet the needs of the various test of ET. It has an important significance to the characteristics research and powertrain parameters matching of ET.
