Construction and Test of Baler Feed Rate Detection Model Based on Power Monitoring

The existing methods of measuring the baler feed rate seldom consider influence machine vibration on sensor signal during field operation, which leads to low detection accuracy and poor stability feeding quantity detection. We established a model based power monitoring pickup platform. Through dynamic analysis platform, functional relationship between working platform was constructed. A system developed, construction experiment performed. mechanism different running speeds torque noise input shaft explored. frequency mainly concentrated at 0.5–6 Hz 9–13 employing fast Fourier transform, eliminated by frequency-domain-filtering method. function processing, determination coefficient R2 0.9796. results show that when is 1.6 4.88 kg/s, RMSE actual predicted are 0.989 0.2, respectively. relative error range feed-rate prediction −9.37–8.77%, indicates has high good meets requirements in operation.
