  METHODS AND RESULTS OF THE SEED MATERIAL FRICTION COEFFICIENT DETERMINING USING AN AUTOMATED DEVICE

  05.20.00 Processes and machines of agroengineering systems

  Description

  The article describes the automated method of friction coefficient determination of row crops seeds using different types of surface, including modern polymer and composite materials. It is revealed that the friction coefficient characterizes the friction properties of seeds arising in the process of mechanical action during harvesting, transportation, storage and processing, as well as changes over time depending on the state of the surfaces, contact time, humidity, relative velocity and other parameters. The problem of lack of friction coefficients values for rest and dynamic friction coefficients for the polymeric and composite materials which are actively applied today at industrial production of agricultural machinery is designated. The design and general view of the device which helps to determine friction coefficient excluding the human factor (operator error) are presented. The operation principle of the developed device is described and the processing method of experimental data is given. Experimental data were obtained and statistical processing was carried out to identify the static and dynamic friction coefficients of seeds. Integral ( ) and differential ( ) graph for the distribution of friction coefficient average values for pairs "type of seed material – type of friction surface" are constructed
