ABSTRACT
The paper presents a mathematical model of the course of the process of threshing in a cereal combine harvester, based on the method of orthogonal polynomials. The model describes the relations between decision variables at threshing input, such as drum rotations, feeding and setting of the threshing slot of the thresher unit, and empirical criterial functions describing the extent of losses in the form of kernels left in ears and threshing damage of grain with different moisture content levels at the time of harvest.

Model procesu powstawania strat w czasie omłotu zbóż kombajnem
kombajnowy zbiór zbóż, straty w czasie omłotu, wielomiany ortogonalne
W prezentowanej pracy przedstawiono model matematyczny przebiegu procesu omłotu w kombajnie zbożowym oparty na metodzie wielomianów ortogonalnych. Model opisuje zależności pomiędzy zmiennymi decyzyjnymi na wejściu procesu omłotu, takimi jak: obroty bębna, zasilanie i szczelina robocza młocarni, a empirycznymi funkcjami kryterialnymi opisującymi wielkość strat w postaci niedomłotu i uszkodzeń młóconego ziarna o różnej wilgotności w czasie zbioru.
