A Way of Estimating the Intensity of Connections Between the Parameters of a Dynamic System

Abstract

In many cases, the influence of some of the characteristic parameters of some systems becomes important in relation to the influence of the other parameters, only when certain critical operating regimes are exceeded. These operating modes are often intangible in normal operation. In order not to endanger the system or to avoid the use of exaggerated power sources, the investigation of the influence of the parameters targeted in these critical operating regimes can be done by simulation, theoretical, experimental or mixed. The results are then subjected to a statistical analysis which may indicate a possible major change in the influence of some of the targeted parameters in the operation of the system. Specifically, the dynamic system considered is an agricultural machine for soil processing, consisting of a combinator and tractor. The simulation is done using a Goriacikin-type formula, which ensures complete theoretical control over the influence of the targeted parameters on the dynamic process of the machine. The parameters we focus on are working depth and working speed. The difference in intensity of the influence of each of the parameters is highlighted, trying an explanation for this difference. The explanations are useful for researchers who want to obtain information about the parameters whose influence on the functioning of the systems is small in the normal working regime but they can grow appreciably in the extra normal working regimes, even if for a short time.
