Grain loss sensor is an important monitoring module to realize the intelligent automatic control in combine harvester. Polyvinylidene fluoride piezoelectricity film has been one of the most widely used macromolecule materials at present. Based on its piezoelectric effect, in this paper, a grain loss monitoring system for combine harvester by using the PVDF sensor was designed. The system is com...

Abstract The work carried out practical testing of the technology thermal diagnostics belt gear elements grating mill drive combine harvester. basis is principle using coefficient temperature ratio on surface diagnosed unit and in friction zone, expressed through proportionality finite element model. peculiarity diagnostics, this case, to compare zone with maximum allowable for direct contact m...
