Abstract

The article presents results generated by research on the influence of forward speed on the traction resistance force for soil processing machines. Statistical estimators are proposed to highlight the intensity of the connection between the traction resistance force and the forward speed and an optimal evaluation method of an exponent of the work speed to explain as well as possible the behaviour of the traction resistance force. It is found that the variance and the standard deviation are the statistical estimators that highlight the most intensively the connection between the traction resistance force and the forward speed.
