Vibration Analysis of a Roller Bearing Condition Used in a Tangential Threshing Drum of a Combine Harvester for the Smooth and Continuous Performance of Agricultural Crop Harvesting

Testing the reliability of threshing unit is difficult and thus often neglected before harvesting season, which can result in breakdown maintenance during peak time difficult-to-access areas for sensor mounting. In this paper, vibration analysis condition combine harvester was performed by introducing bracket inaccessible locations. The Adash A4900 Vibrio M analyzer (Adash spol. s.r.o., Ostrava, Czech Republic) used a signal measurement DDS software processing. demodulated fast Fourier transform (FFT) root mean square (RMS) (500 Hz–16 kHz) method to evaluate bearing Fault Source Identification Tool (FASIT) technology other mechanical conditions such as looseness, misalignment, unbalance Massey Ferguson series harvesters. Modal random analyses were on components compared prevent resonance phenomenon using Ansys Software (Ansys, Inc., Canonsburg, PA, USA). constrained modal drum observe deformation. Decent results obtained from used. again validated tangential test bench successfully determined fault condition. an uncomplicated effective way performing harvester.
