Construction of a regression model for assessing the efficiency of separation of lightweight seeds on vibratory machines involving measures to reduce the harmful influence of the aerodynamic factor

When separating (cleaning) lightweight seed mixtures with the help of vibratory machines, there is an issue related to harmful effect air movement in gaps between parallel working surfaces machine units. This factor particularly material, which sensitive (some medicinal and vegetable crops). To address this issue, design machines changed while their operational regimes are configured accordingly. requires many full-scale experiments (or) time-consuming personal computer-based simulation processes vibrational motion such mixtures. paper proposes several regression models that make it possible replace numerical modeling simple analytical expressions (regression equations). These equations used for a quantitative assessment degree influence aerodynamics on kinematic parameters particles The derived depending geometric characteristics aerodynamic screen, unit, amplitude oscillations machine. take form multiple linear second order, obtained basis series experiments. vibration material parsnips, lettuce, fragrant dill were investigated. coefficient determination equaled 0.956...0.967. results reported here useful construction algorithms optimize adjust operating modes separators according criterion minimizing effects
