Correlation function and spectral density of traction force of machines and tools for cultivation

Correlational function and spectral density are determined for traction force of the ploughing aggregate that consists of the plough “ Orač 2” and the tractor TD 9006 with increased adhesion weight. The form of the standardized correlation function undoubtedly indicates that the traction force consists of random and periodical components. According to the graph of the standardized spectral density, the process of ploughing is of low frequency concerning the structure of traction force.
