Combined system of automatic flow stabilization bread mass at the entry of the thresher of the grain harvester

Abstract

The research conducted in this article is devoted to solving the actual problem of loading the grain harvester with bread mass at the entrance of the thresher. It is possible to achieve the minimum level of fluctuations in the flow of bread mass at the entrance of the threshing-separating device only in appropriately designed optimal multidimensional stabilization systems. At the same time, the methods of dynamic design and analytical design should be used for the construction of similar systems. We proposed to extend the experimental and analytical approach to the design of optimal stabilization systems to the case when minimal fluctuations in the flow of bread mass occur at the entrance to the thresher of the grain harvester. As a result, we developed and implemented an optimal combined system of automatic stabilization with feedback on the deviation from the average value of the flow of bread mass and correction according to the change in output. To carry out the above studies, the method of analyzing the quality of stabilization under random steady-state effects was used, and this made it possible to calculate normalized indicators of the quality of stabilization.
