Information × Registration Number 0211U006281, 0109U002299 , R & D reports Title Ground of parameters and development of barbell small sprinkler for a field-crop cultivation popup.stage_title Head Rybak Timofiy Ivanovich, Registration Date 04-03-2011 Organization Ternopil National Technical Ivan Puluj University popup.description2 A mathematical model which describes the dynamic processes of motion of small sprinkler on processing areas is created. Analytical dependences are got which амплитудно- and phase-frequency descriptions of vibrations of resulted the masses of sprinkler are built on the basis of. Such operating descriptions, as rate of movement, are got, acceleration in the centers of basic the masses, angulators and angular accelerations. The system of differential equalizations which describe the dynamics of motion of small sprinkler is made, the numerical decision of this system is executed. Analytical dependences are got for determination of coefficients dynamic in the proper crossings of sprinkler. Experimental researches are conducted from determination of the real dynamics of small sprinkler. On the basis of calculations, on the developed engineering method, grounded structural parameters of pendant and replacement of hard elements is conducted resilient. High efficiency of work of the improved sprinkler is tested at experimental tests, where found out the considerable improvement of implementation of technological process of sprinkling at the mionectic coefficients of dynamic.
