Abstract

This article presents the results of statistical modeling using experimental results obtained with an organic fertilizer spreading machine having a spreading device that consists of vertical helical rotors. Exposed statistical models are embodied in functions that connect input parameters, command parameters and output parameters of the process in order to estimate machine qualities and optimize the working process. It also shows global qualitative results, along with the profiling of some research methods on experiment groups characterized by different sets of values of the considered working regime parameters.

Abstract in Romanian, Moldavian, Moldovan

Acest articol prezinta rezultatele modelarii statistice folosind rezultatele experimentale obţinute cu o mașină de administrat îngrășăminte organice al cărui dispozitiv de împrăștiere este format din rotoare elicoidale dispuse în plan vertical. Modelele statistice expuse se concretizează în funcții care leagă parametrii de intrare, parametrii de comandă şi parametrii de ieșire ai procesului, în scopul estimării calităților mașinii şi a optimizării procesului de lucru realizat. De asemenea, se expun şi rezultate calitative globale, alături de profilarea unor metode de studiu pe grupuri de experimente, caracterizate de seturi diferite de valori ale parametrilor regimului de lucru considerați.
